NVD Description

Note: Versions mentioned in the description apply only to the upstream libytnef package and not the libytnef package as distributed by Debian. See How to fix? for Debian:12 relevant fixed versions and status.

In ytnef 1.9.3, the SwapWord function in lib/ytnef.c allows remote attackers to cause a denial-of-service (and potentially code execution) due to a heap buffer overflow which can be triggered via a crafted file.
