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

Description A security flaw exists in the Dwggrep Utility component within the dwggrep.c file. A local attacker can cause a null pointer dereference, which occurs when a program attempts to read or write to a memory location that is null, typically leading to a crash, by manipulating the match BLOCK HEADER() function.

Recommendations Update to a version later than 0.14. As a temporary workaround, restrict the use of the match BLOCK HEADER() function within the Dwggrep Utility.
