| Título | LibreDWG Project LibreDWG <= 0.14, main branch up to commit 6d6a339 (2026-04-10) NULL Pointer Dereference (CWE-476) |
|---|
| Descrição | A NULL pointer dereference 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 match_BLOCK_HEADER function when processing maliciously crafted DWG files. Due to insufficient NULL pointer validation during BLOCK_HEADER object matching processing, the code performs an invalid read access to a NULL address. An attacker can exploit this issue by supplying a specially crafted DWG file to the dwggrep utility linked against the vulnerable library, resulting in a program crash and denial of service. |
