CVE-2022-29824 is fixed in 9 products on 1 platform, first by libxml2 2.9.4+dfsg1-6.1ubuntu1.6, released May 2, 2022. It is not reported as exploited. Patch Radar priority: High.
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.
