| Titolo | LibreDWG Project LibreDWG <= 0.14, main branch up to commit 6d6a339 (2026-04-10) NULL Pointer Dereference (CWE-476) |
|---|
| Descrizione | 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 (2026-04-10). The vulnerability occurs in the dwg_next_entity function during entity traversal when processing maliciously crafted DWG files. Due to insufficient validation of decompressed section data, the code dereferences a NULL pointer, resulting in a program crash. An attacker can exploit this issue by supplying a specially crafted DWG file to applications like dwg2SVG, leading to denial of service. The vulnerability was fixed in commit 8f03865 on April 23, 2026. |
