NVD Description

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

Antiword through 0.37 contains a heap out-of-bounds read vulnerability in vGet8LstInfo in prop8.c caused by an inverted bounds check on the PlcfLst record count. Attackers can supply a crafted Word 8 .doc file claiming up to 0xffff LSTF records in a tiny buffer, causing reads past the heap allocation that crash the process.
