MGASA-2022-0177 - Updated libxml2 packages fix security vulnerability

Publication date: 12 May 2022
URL: https://advisories.mageia.org/MGASA-2022-0177.html
Type: security
Affected Mageia releases: 8
CVE: CVE-2022-29824

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.
