|---|
| Mô tả | A heap-based out-of-bounds read vulnerability exists in the LibreDWG library, affecting versions up to and including 0.14, and the main branch up to commit 6d6a339 released on 2026-04-10. The vulnerability occurs in the bit_read_RC function during R2004 compressed section decompression when processing maliciously crafted DWG files. Due to insufficient boundary validation, the code performs an invalid out-of-bounds heap read access. An attacker can exploit this issue by supplying a specially crafted DWG file to the dwgbmp utility linked against the vulnerable library, resulting in a program crash and denial of service. This issue is suspected to be an incomplete fix for a previously reported vulnerability. |
