| Título | LibreDWG libredwg main branch @0b57303 (latest as of 2026-04-29) Heap-buffer-overflow (Out-of-bounds Heap Read) |
|---|
| Descrição | LibreDWG is an open-source library for reading and writing DWG files. A heap buffer overflow vulnerability has been discovered in its dwgbmp utility.
When processing a malformed DWG file, an out-of-bounds heap read operation occurs in the bit_read_RC() function at src/bits.c:281 during the decompression of R2004 compressed sections. This vulnerability can be exploited by a malicious attacker to cause a denial of service (application crash) by crafting a specially designed DWG file.
This vulnerability is related to issue #1248. The developer has submitted a fix commit (87c63bf) on May 3, 2026, which addresses this issue by checking section address bounds and clamping data_size. |
