|---|---|---|---|---|---|
| CVE-2026-62254 | 5.5 medium | — | libredwg | LibreDWG is a free C library to read and write DWG files. Prior to 0.14, a specially crafted R13-R2000 DWG can trigger algorithmic resource exhaustion in `decode_R13_R2000` in `src/decode.c`. The class-decoding loop performs `realloc` on every iteration without a sanity check on `num_classes`. Manipulating that field forces an extremely slow allocation loop and denial of service when the file is parsed. Running the parser in a sandbox with memory limits is a workaround rather than a remediation. This issue is fixed in version 0.14. | 18 h ago |
| CVE-2026-62250 | 5.5 medium | — | libredwg | LibreDWG is a free C library to read and write DWG files. Prior to 0.14.8413, a crafted pre-R13 DWG can make `decode_preR13_entities()` in `src/decode.c` enter a nonterminating loop that allocates a new object each iteration. `decode_preR13` in `src/decode_r11.c` computes `size` from the raw file-controlled `entities_start` and `entities_end` header bounds; the callee clamps `end` to `dat->size` but never recalculates `size`. At `end` of input, `bit_read_RC` and `bit_read_RS` stop advancing `dat->byte`, the overflow guard fails because `end` equals `dat->size`, and the no-advance check compares against `oldpos` saved before the loop instead of the previous iteration. This leaves repeated allocation of `dwg->object` entries until allocation fails or the process is OOM-killed, not merely a constant-memory CPU hang. The defect remains after the clamping and no-progress changes associated with the earlier issue 1131. Applications and tools calling `dwg_read_file()` on untrusted files, including `dwg2dxf`, `dwgread` and `dwg2svg`, can suffer denial of service when a user or automated pipeline opens a malformed file; no attacker credentials are required. This issue is fixed in repository nightly version 0.14.8413. | 18 h ago |
| CVE-2026-54610 | 3.3 low | — | libredwg | LibreDWG is a free C library to read and write DWG files. Prior to 0.14, `bit_TV_to_utf8()` in `src/bits.c` can write to the caller-provided `src` buffer despite accepting const input. On an `iconv()` error other than `E2BIG`, the function frees its output buffer and passes the original input alias to `bit_u_expand()`, which expands or shrinks Unicode and multibyte escape sequences in place. If the input is a string literal, read-only mapping, or other immutable buffer, the write can cause a segmentation fault and denial of service; mutable caller-owned input can be unexpectedly modified before being returned. This affects applications that expose the conversion API to untrusted input under those conditions. Direct file-triggered exploitability through normal DWG decode/export paths remains unconfirmed because many TV strings are heap allocated by bit_read_TV(). This issue is fixed in version 0.14. | 20 h ago |
