NVD Description

Note: Versions mentioned in the description apply only to the upstream libxml2-static package and not the libxml2-static package as distributed by AlmaLinux.

A flaw was found in libxml2's xmlBuildQName function, where integer overflows in buffer size calculations can lead to a stack-based buffer overflow. This issue can result in memory corruption or a denial of service when processing crafted input.
