NVD Description

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

libexpat before 2.8.0 uses insufficient entropy, and thus hash flooding can occur via a crafted XML document.
