|---|---|---|---|---|---|
| CVE-2021-3449exploit | 5.9 medium | 64.0% | openssl, debian, debian_linux, freebsd | An OpenSSL TLS server may crash if sent a maliciously crafted renegotiation ClientHello message from a client. If a TLSv1.2 renegotiation ClientHello omits the signature_algorithms extension (where it was present in the initial ClientHello), but includes a signature_algorithms_cert extension then a NULL pointer dereference will result, leading to a crash and a denial of service attack. A server is only vulnerable if it has TLSv1.2 and renegotiation enabled (which is the default configuration). OpenSSL TLS clients are not impacted by this issue. All OpenSSL 1.1.1 versions are affected by this issue. Users of these versions should upgrade to OpenSSL 1.1.1k. OpenSSL 1.0.2 is not impacted by this issue. Fixed in OpenSSL 1.1.1k (Affected 1.1.1-1.1.1j). | 8 Oct |
| CVE-2021-22924exploit | 3.7 low | 6.0% | haxx, fedoraproject, libcurl, fedora, debian_linux | libcurl keeps previously used connections in a connection pool for subsequenttransfers to reuse, if one of them matches the setup.Due to errors in the logic, the config matching function did not take 'issuercert' into account and it compared the involved paths *case insensitively*,which could lead to libcurl reusing wrong connections.File paths are, or can be, case sensitive on many systems but not all, and caneven vary depending on used file systems.The comparison also didn't include the 'issuer cert' which a transfer can setto qualify how to verify the server certificate. | 14 Oct |
| CVE-2021-22901 | 8.1 high | 64.0% | haxx, oracle, curl, communications_cloud_native_core_binding_support_function, communications_cloud_native_core_network_function_cloud_native_environment | curl 7.75.0 through 7.76.1 suffers from a use-after-free vulnerability resulting in already freed memory being used when a TLS 1.3 session ticket arrives over a connection. A malicious server can use this in rare unfortunate circumstances to potentially reach remote code execution in the client. When libcurl at run-time sets up support for TLS 1.3 session tickets on a connection using OpenSSL, it stores pointers to the transfer in-memory object for later retrieval when a session ticket arrives. If the connection is used by multiple transfers (like with a reused HTTP/1.1 connection or multiplexed HTTP/2 connection) that first transfer object might be freed before the new session is established on that connection and then the function will access a memory buffer that might be freed. When using that memory, libcurl might even call a function pointer in the object, making it possible for a remote code execution if the server could somehow manage to get crafted memory content into the correct place in memory. | 14 Oct |
| CVE-2021-22926 | 7.5 high | 15.0% | haxx, netapp, curl, active_iq_unified_manager, clustered_data_ontap | libcurl-using applications can ask for a specific client certificate to be used in a transfer. This is done with the `CURLOPT_SSLCERT` option (`--cert` with the command line tool).When libcurl is built to use the macOS native TLS library Secure Transport, an application can ask for the client certificate by name or with a file name - using the same option. If the name exists as a file, it will be used instead of by name.If the appliction runs with a current working directory that is writable by other users (like `/tmp`), a malicious user can create a file name with the same name as the app wants to use by name, and thereby trick the application to use the file based cert instead of the one referred to by name making libcurl send the wrong client certificate in the TLS connection handshake. | 14 Oct |
| CVE-2019-19603 | 7.5 high | 11.0% | sqlite, oracle, mysql_workbench, sinec_infrastructure_network_services | SQLite 3.30.1 mishandles certain SELECT statements with a nonexistent VIEW, leading to an application crash. | 14 Oct |
| CVE-2019-19924 | 5.3 medium | 11.0% | sqlite, siemens, sinec_infrastructure_network_services, bookkeeper | SQLite 3.30.1 mishandles certain parser-tree rewriting, related to expr.c, vdbeaux.c, and window.c. This is caused by incorrect sqlite3WindowRewrite() error handling. | 14 Oct |
| CVE-2020-8285 | 7.5 high | 10.0% | haxx, debian, libcurl, debian_linux, fedora | curl 7.21.0 to and including 7.73.0 is vulnerable to uncontrolled recursion due to a stack overflow issue in FTP wildcard match parsing. | 14 Oct |
| CVE-2020-11656 | 9.8 critical | 9.0% | sqlite, netapp, ontap_select_deploy_administration_utility, communications_network_charging_and_control | In SQLite through 3.31.1, the ALTER TABLE implementation has a use-after-free, as demonstrated by an ORDER BY clause that belongs to a compound SELECT statement. | 14 Oct |
| CVE-2019-19926 | 7.5 high | 8.0% | sqlite, siemens, sinec_infrastructure_network_services, mysql_workbench | multiSelect in select.c in SQLite 3.30.1 mishandles certain errors during parsing, as demonstrated by errors from sqlite3WindowRewrite() calls. NOTE: this vulnerability exists because of an incomplete fix for CVE-2019-19880. | 14 Oct |
| CVE-2019-19646 | 9.8 critical | 7.0% | sqlite, siemens, sinec_infrastructure_network_services, tenable.sc | pragma.c in SQLite through 3.30.1 mishandles NOT NULL in an integrity_check PRAGMA command in certain cases of generated columns. | 14 Oct |
| CVE-2019-19925 | 7.5 high | 7.0% | sqlite, siemens, sinec_infrastructure_network_services, mysql_workbench | zipfileUpdate in ext/misc/zipfile.c in SQLite 3.30.1 mishandles a NULL pathname during an update of a ZIP archive. | 14 Oct |
| CVE-2019-19923 | 7.5 high | 7.0% | sqlite, siemens, sinec_infrastructure_network_services, mysql_workbench | flattenSubquery in select.c in SQLite 3.30.1 mishandles certain uses of SELECT DISTINCT involving a LEFT JOIN in which the right-hand side is a view. This can cause a NULL pointer dereference (or incorrect results). | 14 Oct |
| CVE-2019-19880 | 7.5 high | 7.0% | sqlite, netapp, cloud_backup, debian_linux | exprListAppendList in window.c in SQLite 3.30.1 allows attackers to trigger an invalid pointer dereference because constant integer values in ORDER BY clauses of window definitions are mishandled. | 14 Oct |
| CVE-2019-19317 | 9.8 critical | 5.0% | sqlite, netapp, cloud_backup, ontap_select_deploy_administration_utility | lookupName in resolve.c in SQLite 3.30.1 omits bits from the colUsed bitmask in the case of a generated column, which allows attackers to cause a denial of service or possibly have unspecified other impact. | 14 Oct |
| CVE-2021-22946 | 7.5 high | 5.0% | haxx, debian, curl, debian_linux, fedora | A user can tell curl >= 7.20.0 and <= 7.78.0 to require a successful upgrade to TLS when speaking to an IMAP, POP3 or FTP server (`--ssl-reqd` on the command line or`CURLOPT_USE_SSL` set to `CURLUSESSL_CONTROL` or `CURLUSESSL_ALL` withlibcurl). This requirement could be bypassed if the server would return a properly crafted but perfectly legitimate response.This flaw would then make curl silently continue its operations **withoutTLS** contrary to the instructions and expectations, exposing possibly sensitive data in clear text over the network. | 14 Oct |
| CVE-2020-8286 | 7.5 high | 5.0% | haxx, fedoraproject, libcurl, fedora, debian_linux | curl 7.41.0 through 7.73.0 is vulnerable to an improper check for certificate revocation due to insufficient verification of the OCSP response. | 14 Oct |
| CVE-2020-8231 | 7.5 high | 5.0% | haxx, siemens, libcurl, sinec_infrastructure_network_services, debian_linux | Due to use of a dangling pointer, libcurl 7.29.0 through 7.71.1 can use the wrong connection when sending data. | 14 Oct |
| CVE-2021-22925 | 5.3 medium | 5.0% | haxx, fedoraproject, curl, fedora, cloud_backup | curl supports the `-t` command line option, known as `CURLOPT_TELNETOPTIONS`in libcurl. This rarely used option is used to send variable=content pairs toTELNET servers.Due to flaw in the option parser for sending `NEW_ENV` variables, libcurlcould be made to pass on uninitialized data from a stack based buffer to theserver. Therefore potentially revealing sensitive internal information to theserver using a clear-text network protocol.This could happen because curl did not call and use sscanf() correctly whenparsing the string provided by the application. | 14 Oct |
| CVE-2021-22876 | 5.3 medium | 5.0% | haxx, fedoraproject, libcurl, fedora, hci_management_node | curl 7.1.1 to and including 7.75.0 is vulnerable to an "Exposure of Private Personal Information to an Unauthorized Actor" by leaking credentials in the HTTP Referer: header. libcurl does not strip off user credentials from the URL when automatically populating the Referer: HTTP request header field in outgoing HTTP requests, and therefore risks leaking sensitive data to the server that is the target of the second HTTP request. | 14 Oct |
| CVE-2021-22898 | 3.1 low | 5.0% | haxx, debian, curl, debian_linux, fedora | curl 7.7 through 7.76.1 suffers from an information disclosure when the `-t` command line option, known as `CURLOPT_TELNETOPTIONS` in libcurl, is used to send variable=content pairs to TELNET servers. Due to a flaw in the option parser for sending NEW_ENV variables, libcurl could be made to pass on uninitialized data from a stack based buffer to the server, resulting in potentially revealing sensitive internal information to the server using a clear-text network protocol. | 14 Oct |
| CVE-2020-13871 | 7.5 high | 4.0% | sqlite, fedoraproject, fedora, debian_linux | SQLite 3.32.2 has a use-after-free in resetAccumulator in select.c because the parse tree rewrite for window functions is too late. | 14 Oct |
| CVE-2020-9327 | 7.5 high | 4.0% | sqlite, netapp, cloud_backup, ubuntu_linux | In SQLite 3.31.1, isAuxiliaryVtabOperator allows attackers to trigger a NULL pointer dereference and segmentation fault because of generated column optimizations. | 14 Oct |
| CVE-2020-8169 | 7.5 high | 4.0% | haxx, siemens, curl, simatic_tim_1531_irc_firmware, debian_linux | curl 7.62.0 through 7.70.0 is vulnerable to an information disclosure vulnerability that can lead to a partial password being leaked over the network and to the DNS server(s). | 14 Oct |
| CVE-2020-11655 | 7.5 high | 4.0% | sqlite, netapp, ontap_select_deploy_administration_utility, debian_linux | SQLite through 3.31.1 allows attackers to cause a denial of service (segmentation fault) via a malformed window-function query because the AggInfo object's initialization is mishandled. | 14 Oct |
| CVE-2019-19244 | 7.5 high | 4.0% | sqlite, canonical, ubuntu_linux, mysql_workbench | sqlite3Select in select.c in SQLite 3.30.1 allows a crash if a sub-select uses both DISTINCT and window functions, and also has certain ORDER BY usage. | 14 Oct |
| CVE-2021-22922 | 6.5 medium | 4.0% | haxx, fedoraproject, curl, fedora, cloud_backup | When curl is instructed to download content using the metalink feature, thecontents is verified against a hash provided in the metalink XML file.The metalink XML file points out to the client how to get the same contentfrom a set of different URLs, potentially hosted by different servers and theclient can then download the file from one or several of them. In a serial orparallel manner.If one of the servers hosting the contents has been breached and the contentsof the specific file on that server is replaced with a modified payload, curlshould detect this when the hash of the file mismatches after a completeddownload. It should remove the contents and instead try getting the contentsfrom another URL. This is not done, and instead such a hash mismatch is onlymentioned in text and the potentially malicious content is kept in the file ondisk. | 14 Oct |
| CVE-2021-22897 | 5.3 medium | 4.0% | haxx, oracle, curl, communications_cloud_native_core_binding_support_function, communications_cloud_native_core_network_function_cloud_native_environment | curl 7.61.0 through 7.76.1 suffers from exposure of data element to wrong session due to a mistake in the code for CURLOPT_SSL_CIPHER_LIST when libcurl is built to use the Schannel TLS library. The selected cipher set was stored in a single "static" variable in the library, which has the surprising side-effect that if an application sets up multiple concurrent transfers, the last one that sets the ciphers will accidentally control the set used by all transfers. In a worst-case scenario, this weakens transport security significantly. | 14 Oct |
| CVE-2020-8284 | 3.7 low | 4.0% | haxx, fedoraproject, curl, fedora, debian_linux | A malicious server can use the FTP PASV response to trick curl 7.73.0 and earlier into connecting back to a given IP address and port, and this way potentially make curl extract information about services that are otherwise private and not disclosed, for example doing port scanning and service banner extractions. | 14 Oct |
| CVE-2021-22947 | 5.9 medium | 3.0% | haxx, fedoraproject, curl, fedora, debian_linux | When curl >= 7.20.0 and <= 7.78.0 connects to an IMAP or POP3 server to retrieve data using STARTTLS to upgrade to TLS security, the server can respond and send back multiple responses at once that curl caches. curl would then upgrade to TLS but not flush the in-queue of cached responses but instead continue using and trustingthe responses it got *before* the TLS handshake as if they were authenticated.Using this flaw, it allows a Man-In-The-Middle attacker to first inject the fake responses, then pass-through the TLS traffic from the legitimate server and trick curl into sending data back to the user thinking the attacker's injected data comes from the TLS-protected server. | 14 Oct |
| CVE-2019-19242 | 5.9 medium | 3.0% | sqlite, canonical, ubuntu_linux, enterprise_linux | SQLite 3.30.1 mishandles pExpr->y.pTab, as demonstrated by the TK_COLUMN case in sqlite3ExprCodeTarget in expr.c. | 14 Oct |
| CVE-2021-22890 | 3.7 low | 3.0% | haxx, fedoraproject, libcurl, fedora, hci_management_node | curl 7.63.0 to and including 7.75.0 includes vulnerability that allows a malicious HTTPS proxy to MITM a connection due to bad handling of TLS 1.3 session tickets. When using a HTTPS proxy and TLS 1.3, libcurl can confuse session tickets arriving from the HTTPS proxy but work as if they arrived from the remote server and then wrongly "short-cut" the host handshake. When confusing the tickets, a HTTPS proxy can trick libcurl to use the wrong session ticket resume for the host and thereby circumvent the server TLS certificate check and make a MITM attack to be possible to perform unnoticed. Note that such a malicious HTTPS proxy needs to provide a certificate that curl will accept for the MITMed server for an attack to work - unless curl has been told to ignore the server certificate check. | 14 Oct |
| CVE-2021-22923 | 5.3 medium | 2.0% | haxx, fedoraproject, curl, fedora, cloud_backup | When curl is instructed to get content using the metalink feature, and a user name and password are used to download the metalink XML file, those same credentials are then subsequently passed on to each of the servers from which curl will download or try to download the contents from. Often contrary to the user's expectations and intentions and without telling the user it happened. | 14 Oct |
| CVE-2020-8177 | 7.8 high | 1.0% | haxx, debian, curl, debian_linux, m10-1_firmware | curl 7.20.0 through 7.70.0 is vulnerable to improper restriction of names for files and other resources that can lead too overwriting a local file when the -J flag is used. | 14 Oct |
| CVE-2020-13630 | 7.0 high | 1.0% | sqlite, fedoraproject, fedora, ubuntu_linux | ext/fts3/fts3.c in SQLite before 3.32.0 has a use-after-free in fts3EvalNextRow, related to the snippet feature. | 14 Oct |
| CVE-2020-15358 | 5.5 medium | 1.0% | sqlite, canonical, ubuntu_linux, icloud | In SQLite before 3.32.3, select.c mishandles query-flattener optimization, leading to a multiSelectOrderBy heap overflow because of misuse of transitive properties for constant propagation. | 14 Oct |
| CVE-2020-13632 | 5.5 medium | 1.0% | sqlite, fedoraproject, fedora, ubuntu_linux | ext/fts3/fts3_snippet.c in SQLite before 3.32.0 has a NULL pointer dereference via a crafted matchinfo() query. | 14 Oct |
| CVE-2020-13631 | 5.5 medium | 1.0% | sqlite, fedoraproject, fedora, ubuntu_linux | SQLite before 3.32.0 allows a virtual table to be renamed to the name of one of its shadow tables, related to alter.c and build.c. | 14 Oct |
| CVE-2019-19645 | 5.5 medium | 1.0% | sqlite, netapp, cloud_backup, ontap_select_deploy_administration_utility | alter.c in SQLite through 3.30.1 allows attackers to trigger infinite recursion via certain types of self-referential views in conjunction with ALTER TABLE statements. | 14 Oct |
