Description Vladimir Vasilev 2026-10-21 08:21:38 UTC

Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

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.
