NVD Description

Note: Versions mentioned in the description apply only to the upstream libextractor package and not the libextractor package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

GNU libextractor before 1.15 contains a stack-based buffer overflow vulnerability in the process_star_office function that sizes a variable-length stack array from attacker-controlled OLE2 stream data. Attackers can craft malicious StarOffice documents that allocate up to 4 MB on the stack, causing stack overflow and crashing any application extracting metadata from the document.
