Name of the Vulnerable Software and Affected Versions GNU LibreDWG versions prior to 0.15

Description A weakness in the Dwgbmp Utility component allows an out-of-bounds read, which occurs when the system reads data outside the intended boundary of a buffer. This issue is located in the read 2004 compressed section() function within the src/decode.c file. Exploitation requires local access.

Recommendations Apply patch 8f03865f37f5d4ffd616fef802acc980be54d300 to resolve the issue. As a temporary workaround, restrict access to the read 2004 compressed section() function to minimize the risk of exploitation.
