Oracle Linux: CVE-2022-29824: ELSA-2022-5250: libxml2 security update (MODERATE) (Multiple Advisories)
Description
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. A flaw was found in the libxml2 library in functions used to manipulate the xmlBuf and the xmlBuffer types. A substantial input causes values to calculate buffer sizes to overflow, resulting in an out-of-bounds write.
