CVE details

CVE-2022-29824

In libxml2 before 2.9.14, several buffer handling functions in buf.c (xmlBuf) and tree.c (xmlBuffer) don't check for integer overflows. This can result in out-of-bounds memory writes. Exploitation requires a victim to open a crafted, multi-gigabyte XML file. Other software using libxml2's buffer functions, for example libxslt through 1.1.35, is affected as well.
