NVD Description
Note: Versions mentioned in the description apply only to the upstream expat package and not the expat package as distributed by AlmaLinux.
See How to fix? for AlmaLinux:9 relevant fixed versions and status.
libexpat through 2.5.0 allows a denial of service (resource consumption) because many full reparsings are required in the case of a large token for which multiple buffer fills are needed.
