| CVE | CVSS | EPSS | Vendor, product | Description | Modified |
|---|---|---|---|---|---|
| CVE-2023-4911KEVexploit ×24 | 7.8 high | 64.0% | netapp, siemens, bootstrap_os, simatic_s7-1500_cpu_1518-4_pn\/dp_mfp_firmware, simatic_s7-1500_cpu_1518f-4_pn\/dp_mfp_firmware | A buffer overflow was discovered in the GNU C Library's dynamic loader ld.so while processing the GLIBC_TUNABLES environment variable. This issue could allow a local attacker to use maliciously crafted GLIBC_TUNABLES environment variables when launching binaries with SUID permission to execute code with elevated privileges. | 14 Oct |
| CVE-2020-13777exploit ×3 | 7.4 high | 22.0% | gnu, fedoraproject, gnutls, fedora, ubuntu_linux | GnuTLS 3.6.x before 3.6.14 uses incorrect cryptography for encrypting a session ticket (a loss of confidentiality in TLS 1.2, and an authentication bypass in TLS 1.3). The earliest affected version is 3.6.4 (2018-09-24) because of an error in a 2018-09-18 commit. Until the first key rotation, the TLS server always uses wrong data in place of an encryption key derived from an application. | 14 Oct |
| CVE-2019-18276exploit ×2 | 7.8 high | 3.0% | gnu, netapp, bash, hci_management_node, oncommand_unified_manager | An issue was discovered in disable_priv_mode in shell.c in GNU Bash through 5.0 patch 11. By default, if Bash is run with its effective UID not equal to its real UID, it will drop privileges by setting its effective UID to its real UID. However, it does so incorrectly. On Linux and other systems that support "saved UID" functionality, the saved UID is not dropped. An attacker with command execution in the shell can use "enable -f" for runtime loading of a new builtin, which can be a shared object that calls setuid() and therefore regains privileges. However, binaries running with an effective UID of 0 are unaffected. | 14 Oct |
| CVE-2023-4813exploit | 5.9 medium | 2.0% | gnu, redhat, glibc, enterprise_linux, enterprise_linux_eus | A flaw has been identified in glibc. In an uncommon situation, the gaih_inet function may use memory that has been freed, resulting in an application crash. This issue is only exploitable when the getaddrinfo function is called and the hosts database in /etc/nsswitch.conf is configured with SUCCESS=continue or SUCCESS=merge. | 14 Oct |
| CVE-2024-0684exploit | 5.5 medium | 0.00% | gnu, coreutils | A flaw was found in the GNU coreutils "split" program. A heap overflow with user-controlled data of multiple hundred bytes in length could occur in the line_bytes_split() function, potentially leading to an application crash and denial of service. | 15 Oct |
| CVE-2025-7545exploit | 1.9 low | 0.00% | gnu, binutils | A vulnerability classified as problematic was found in GNU Binutils 2.45. Affected by this vulnerability is the function copy_section of the file binutils/objcopy.c. The manipulation leads to heap-based buffer overflow. Attacking locally is a requirement. The exploit has been disclosed to the public and may be used. The patch is named 08c3cbe5926e4d355b5cb70bbec2b1eeb40c2944. It is recommended to apply a patch to fix this issue. | 15 Oct |
| CVE-2022-1271 | 8.8 high | 6.0% | gnu, redhat, gzip, jboss_data_grid, debian_linux | An arbitrary file write vulnerability was found in GNU gzip's zgrep utility. When zgrep is applied on the attacker's chosen file name (for example, a crafted file name), this can overwrite an attacker's content to an arbitrary attacker-selected file. This flaw occurs due to insufficient validation when processing filenames with two or more newlines where selected content and the target file names are embedded in crafted multi-line file names. This flaw allows a remote, low privileged attacker to force zgrep to write arbitrary files on the system. | 14 Oct |
| CVE-2018-19591 | 7.5 high | 6.0% | gnu, fedoraproject, glibc, fedora | In the GNU C Library (aka glibc or libc6) through 2.28, attempting to resolve a crafted hostname via getaddrinfo() leads to the allocation of a socket descriptor that is not closed. This is related to the if_nametoindex() function. | 14 Oct |
| CVE-2022-23219 | 9.8 critical | 5.0% | gnu, oracle, glibc, communications_cloud_native_core_binding_support_function, communications_cloud_native_core_network_function_cloud_native_environment | The deprecated compatibility function clnt_create in the sunrpc module of the GNU C Library (aka glibc) through 2.34 copies its hostname argument on the stack without validating its length, which may result in a buffer overflow, potentially resulting in a denial of service or (if an application is not built with a stack protector enabled) arbitrary code execution. | 14 Oct |
| CVE-2022-23218 | 9.8 critical | 5.0% | gnu, oracle, glibc, communications_cloud_native_core_unified_data_repository, enterprise_operations_monitor | The deprecated compatibility function svcunix_create in the sunrpc module of the GNU C Library (aka glibc) through 2.34 copies its path argument on the stack without validating its length, which may result in a buffer overflow, potentially resulting in a denial of service or (if an application is not built with a stack protector enabled) arbitrary code execution. | 14 Oct |
| CVE-2019-9169 | 9.8 critical | 5.0% | gnu, netapp, glibc, cloud_backup, ontap_select_deploy_administration_utility | In the GNU C Library (aka glibc or libc6) through 2.29, proceed_next_node in posix/regexec.c has a heap-based buffer over-read via an attempted case-insensitive regular-expression match. | 14 Oct |
| CVE-2020-6096 | 8.1 high | 5.0% | gnu, fedoraproject, glibc, fedora, debian_linux | An exploitable signed comparison vulnerability exists in the ARMv7 memcpy() implementation of GNU glibc 2.30.9000. Calling memcpy() (on ARMv7 targets that utilize the GNU glibc implementation) with a negative value for the 'num' parameter results in a signed comparison vulnerability. If an attacker underflows the 'num' parameter to memcpy(), this vulnerability could lead to undefined behavior such as writing to out-of-bounds memory and potentially remote code execution. Furthermore, this memcpy() implementation allows for program execution to continue in scenarios where a segmentation fault or crash should have occurred. The dangers occur in that subsequent execution and iterations of this code will be executed with this corrupted data. | 14 Oct |
| CVE-2021-33574 | 9.8 critical | 4.0% | gnu, fedoraproject, glibc, fedora, cloud_backup | The mq_notify function in the GNU C Library (aka glibc) versions 2.32 and 2.33 has a use-after-free. It may use the notification thread attributes object (passed through its struct sigevent parameter) after it has been freed by the caller, leading to a denial of service (application crash) or possibly unspecified other impact. | 14 Oct |
| CVE-2021-20231 | 9.8 critical | 4.0% | gnu, redhat, gnutls, enterprise_linux, fedora | A flaw was found in gnutls. A use after free issue in client sending key_share extension may lead to memory corruption and other consequences. | 14 Oct |
| CVE-2019-18224 | 9.8 critical | 4.0% | gnu, libidn2 | idn2_to_ascii_4i in lib/lookup.c in GNU libidn2 before 2.1.1 has a heap-based buffer overflow via a long domain string. | 14 Oct |
| CVE-2021-43618 | 7.5 high | 4.0% | gmplib, debian, gmp, debian_linux, active_iq_unified_manager | GNU Multiple Precision Arithmetic Library (GMP) through 6.2.1 has an mpz/inp_raw.c integer overflow and resultant buffer overflow via crafted input, leading to a segmentation fault on 32-bit platforms. | 14 Oct |
| CVE-2021-38604 | 7.5 high | 4.0% | gnu, fedoraproject, glibc, fedora, communications_cloud_native_core_binding_support_function | In librt in the GNU C Library (aka glibc) through 2.34, sysdeps/unix/sysv/linux/mq_notify.c mishandles certain NOTIFY_REMOVED data, leading to a NULL pointer dereference. NOTE: this vulnerability was introduced as a side effect of the CVE-2021-33574 fix. | 14 Oct |
| CVE-2021-3326 | 7.5 high | 4.0% | gnu, netapp, glibc, e-series_santricity_os_controller, ontap_select_deploy_administration_utility | The iconv function in the GNU C Library (aka glibc or libc6) 2.32 and earlier, when processing invalid input sequences in the ISO-2022-JP-3 encoding, fails an assertion in the code path and aborts the program, potentially resulting in a denial of service. | 14 Oct |
| CVE-2020-24659 | 7.5 high | 4.0% | gnu, fedoraproject, gnutls, fedora, leap | An issue was discovered in GnuTLS before 3.6.15. A server can trigger a NULL pointer dereference in a TLS 1.3 client if a no_renegotiation alert is sent with unexpected timing, and then an invalid second handshake occurs. The crash happens in the application's error handling path, where the gnutls_deinit function is called after detecting a handshake failure. | 14 Oct |
| CVE-2019-25013 | 5.9 medium | 4.0% | gnu, fedoraproject, glibc, fedora, ontap_select_deploy_administration_utility | The iconv feature in the GNU C Library (aka glibc or libc6) through 2.32, when processing invalid multi-byte input sequences in the EUC-KR encoding, may have a buffer over-read. | 14 Oct |
| CVE-2016-10228 | 5.9 medium | 4.0% | gnu, glibc | The iconv program in the GNU C Library (aka glibc or libc6) 2.31 and earlier, when invoked with multiple suffixes in the destination encoding (TRANSLATE or IGNORE) along with the -c option, enters an infinite loop when processing invalid multi-byte input sequences, leading to a denial of service. | 14 Oct |
| CVE-2021-20232 | 9.8 critical | 3.0% | gnu, redhat, gnutls, enterprise_linux, fedora | A flaw was found in gnutls. A use after free issue in client_send_params in lib/ext/pre_shared_key.c may lead to memory corruption and other potential consequences. | 14 Oct |
| CVE-2019-1010022 | 9.8 critical | 3.0% | gnu, glibc | GNU Libc current is affected by: Mitigation bypass. The impact is: Attacker may bypass stack guard protection. The component is: nptl. The attack vector is: Exploit stack buffer overflow vulnerability and use this bypass vulnerability to bypass stack guard. NOTE: Upstream comments indicate "this is being treated as a non-security bug and no real threat. | 14 Oct |
| CVE-2021-46848 | 9.1 critical | 3.0% | gnu, fedoraproject, libtasn1, fedora, debian_linux | GNU Libtasn1 before 4.19.0 has an ETYPE_OK off-by-one array size check that affects asn1_encode_simple_der. | 14 Oct |
| CVE-2021-35942 | 9.1 critical | 3.0% | gnu, netapp, glibc, active_iq_unified_manager, e-series_santricity_os_controller | The wordexp function in the GNU C Library (aka glibc) through 2.33 may crash or read arbitrary memory in parse_param (in posix/wordexp.c) when called with an untrusted, crafted pattern, potentially resulting in a denial of service or disclosure of information. This occurs because atoi was used but strtoul should have been used to ensure correct calculations. | 14 Oct |
| CVE-2018-12886 | 8.1 high | 3.0% | gnu, gcc | stack_protect_prologue in cfgexpand.c and stack_protect_epilogue in function.c in GNU Compiler Collection (GCC) 4.1 through 8 (under certain circumstances) generate instruction sequences when targeting ARM targets that spill the address of the stack protector guard, which allows an attacker to bypass the protection of -fstack-protector, -fstack-protector-all, -fstack-protector-strong, and -fstack-protector-explicit against stack overflow by controlling what the stack canary is compared against. | 14 Oct |
| CVE-2019-1010180 | 7.8 high | 3.0% | gnu, opensuse, gdb, leap | GNU gdb All versions is affected by: Buffer Overflow - Out of bound memory access. The impact is: Deny of Service, Memory Disclosure, and Possible Code Execution. The component is: The main gdb module. The attack vector is: Open an ELF for debugging. The fixed version is: Not fixed yet. | 14 Oct |
| CVE-2021-43396 | 7.5 high | 3.0% | gnu, oracle, glibc, communications_cloud_native_core_binding_support_function, communications_cloud_native_core_network_function_cloud_native_environment | In iconvdata/iso-2022-jp-3.c in the GNU C Library (aka glibc) 2.34, remote attackers can force iconv() to emit a spurious '\0' character via crafted ISO-2022-JP-3 data that is accompanied by an internal state reset. This may affect data integrity in certain iconv() use cases. NOTE: the vendor states "the bug cannot be invoked through user input and requires iconv to be invoked with a NULL inbuf, which ought to require a separate application bug to do so unintentionally. Hence there's no security impact to the bug. | 14 Oct |
| CVE-2020-29573 | 7.5 high | 3.0% | gnu, redhat, glibc, enterprise_linux, cloud_backup | sysdeps/i386/ldbl2mpn.c in the GNU C Library (aka glibc or libc6) before 2.23 on x86 targets has a stack-based buffer overflow if the input to any of the printf family of functions is an 80-bit long double with a non-canonical bit pattern, as seen when passing a \x00\x04\x00\x00\x00\x00\x00\x00\x00\x04 value to sprintf. NOTE: the issue does not affect glibc by default in 2016 or later (i.e., 2.23 or later) because of commits made in 2015 for inlining of C99 math functions through use of GCC built-ins. In other words, the reference to 2.23 is intentional despite the mention of "Fixed for glibc 2.33" in the 26649 reference. | 14 Oct |
| CVE-2019-9923 | 7.5 high | 3.0% | gnu, opensuse, tar, leap | pax_decode_header in sparse.c in GNU Tar before 1.32 had a NULL pointer dereference when parsing certain archives that have malformed extended headers. | 14 Oct |
| CVE-2019-15847 | 7.5 high | 3.0% | gnu, opensuse, gcc, leap | The POWER9 backend in GNU Compiler Collection (GCC) before version 10 could optimize multiple calls of the __builtin_darn intrinsic into a single call, thus reducing the entropy of the random number generator. This occurred because a volatile operation was not specified. For example, within a single execution of a program, the output of every __builtin_darn() call may be the same. | 14 Oct |
| CVE-2019-12290 | 7.5 high | 3.0% | gnu, libidn2 | GNU libidn2 before 2.2.0 fails to perform the roundtrip checks specified in RFC3490 Section 4.2 when converting A-labels to U-labels. This makes it possible in some circumstances for one domain to impersonate another. By creating a malicious domain that matches a target domain except for the inclusion of certain punycoded Unicode characters (that would be discarded when converted first to a Unicode label and then back to an ASCII label), arbitrary domains can be impersonated. | 14 Oct |
| CVE-2020-11501 | 7.4 high | 3.0% | gnu, canonical, gnutls, ubuntu_linux, debian_linux | GnuTLS 3.6.x before 3.6.13 uses incorrect cryptography for DTLS. The earliest affected version is 3.6.3 (2018-07-16) because of an error in a 2017-10-06 commit. The DTLS client always uses 32 '\0' bytes instead of a random value, and thus contributes no randomness to a DTLS negotiation. This breaks the security guarantees of the DTLS protocol. | 14 Oct |
| CVE-2019-1010023 | 5.4 medium | 3.0% | gnu, glibc | GNU Libc current is affected by: Re-mapping current loaded library with malicious ELF file. The impact is: In worst case attacker may evaluate privileges. The component is: libld. The attack vector is: Attacker sends 2 ELF files to victim and asks to run ldd on it. ldd execute code. NOTE: Upstream comments indicate "this is being treated as a non-security bug and no real threat. | 14 Oct |
| CVE-2019-1010024 | 5.3 medium | 3.0% | gnu, glibc | GNU Libc current is affected by: Mitigation bypass. The impact is: Attacker may bypass ASLR using cache of thread stack and heap. The component is: glibc. NOTE: Upstream comments indicate "this is being treated as a non-security bug and no real threat. | 14 Oct |
| CVE-2015-1197 | 1.9 low | 3.0% | gnu, cpio | cpio 2.11, when using the --no-absolute-filenames option, allows local users to write to arbitrary files via a symlink attack on a file in an archive. | 14 Oct |
| CVE-2026-33845 | 9.1 critical | 2.0% | gnu, redhat, gnutls, openshift_container_platform, enterprise_linux | A flaw in GnuTLS DTLS handshake parsing allows malformed fragments with zero length and non-zero offset, leading to an integer underflow during reassembly and resulting in an out-of-bounds read. This issue is remotely exploitable and may cause information disclosure or denial of service. | Mon 26 Oct |
| CVE-2026-9155 | 8.8 high | 2.0% | gnu, sed | OS Command Injection vulnerability in Rapid7 InsightConnect Sed Plugin on Linux allows authenticated attackers to execute arbitrary OS commands via the expression parameter due to insufficient input validation. | Sun 25 Oct |
| CVE-2024-0553 | 7.5 high | 2.0% | gnu, fedoraproject, gnutls, fedora, enterprise_linux | A vulnerability was found in GnuTLS. The response times to malformed ciphertexts in RSA-PSK ClientKeyExchange differ from the response times of ciphertexts with correct PKCS#1 v1.5 padding. This issue may allow a remote attacker to perform a timing side-channel attack in the RSA-PSK key exchange, potentially leading to the leakage of sensitive data. CVE-2024-0553 is designated as an incomplete resolution for CVE-2023-5981. | 15 Oct |
| CVE-2023-5156 | 7.5 high | 2.0% | gnu, redhat, glibc, enterprise_linux | A flaw was found in the GNU C Library. A recent fix for CVE-2023-4806 introduced the potential for a memory leak, which may result in an application crash. | 14 Oct |
| CVE-2022-2509 | 7.5 high | 2.0% | gnu, redhat, gnutls, enterprise_linux, fedora | A vulnerability found in gnutls. This security flaw happens because of a double free error occurs during verification of pkcs7 signatures in gnutls_pkcs7_verify function. | 14 Oct |
| CVE-2021-3998 | 7.5 high | 2.0% | gnu, netapp, glibc, ontap_select_deploy_administration_utility, h300s_firmware | A flaw was found in glibc. The realpath() function can mistakenly return an unexpected value, potentially leading to information leakage and disclosure of sensitive data. | 14 Oct |
| CVE-2021-4209 | 6.5 medium | 2.0% | gnu, redhat, gnutls, enterprise_linux, active_iq_unified_manager | A NULL pointer dereference flaw was found in GnuTLS. As Nettle's hash update functions internally call memcpy, providing zero-length input may cause undefined behavior. This flaw leads to a denial of service after authentication in rare circumstances. | 14 Oct |
| CVE-2021-3826 | 6.5 medium | 2.0% | gnu, fedoraproject, gcc, fedora | Heap/stack buffer overflow in the dlang_lname function in d-demangle.c in libiberty allows attackers to potentially cause a denial of service (segmentation fault and crash) via a crafted mangled symbol. | 14 Oct |
| CVE-2018-18700 | 5.5 medium | 2.0% | gnu, binutils | An issue was discovered in cp-demangle.c in GNU libiberty, as distributed in GNU Binutils 2.31. There is a stack consumption vulnerability resulting from infinite recursion in the functions d_name(), d_encoding(), and d_local_name() in cp-demangle.c. Remote attackers could leverage this vulnerability to cause a denial-of-service via an ELF file, as demonstrated by nm. | 15 Oct |
| CVE-2019-12972 | 5.5 medium | 2.0% | gnu, opensuse, binutils, leap, ubuntu_linux | An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.32. There is a heap-based buffer over-read in _bfd_doprnt in bfd.c because elf_object_p in elfcode.h mishandles an e_shstrndx section of type SHT_GROUP by omitting a trailing '\0' character. | 8 Oct |
| CVE-2019-14250 | 5.5 medium | 2.0% | gnu, canonical, binutils, ubuntu_linux, leap | An issue was discovered in GNU libiberty, as distributed in GNU Binutils 2.32. simple_object_elf_match in simple-object-elf.c does not check for a zero shstrndx value, leading to an integer overflow and resultant heap-based buffer overflow. | 8 Oct |
| CVE-2019-1010025 | 5.3 medium | 2.0% | gnu, glibc | GNU Libc current is affected by: Mitigation bypass. The impact is: Attacker may guess the heap addresses of pthread_created thread. The component is: glibc. NOTE: the vendor's position is "ASLR bypass itself is not a vulnerability. | 14 Oct |
| CVE-2020-29562 | 4.8 medium | 2.0% | gnu, fedoraproject, glibc, fedora, e-series_santricity_os_controller | The iconv function in the GNU C Library (aka glibc or libc6) 2.30 to 2.32, when converting UCS4 text containing an irreversible character, fails an assertion in the code path and aborts the program, potentially resulting in a denial of service. | 14 Oct |
| CVE-2026-42010 | 9.8 critical | 1.0% | gnu, redhat, gnutls, hardened_images, openshift_container_platform | A flaw was found in gnutls. Servers configured with RSA-PSK (Rivest–Shamir–Adleman – Pre-Shared Key) wrongfully matched usernames containing a NUL character with truncated usernames. A remote attacker could exploit this by sending a specially crafted username, leading to an authentication bypass. This vulnerability allows an attacker to gain unauthorized access by circumventing the authentication process. | Mon 26 Oct |
