CentOS 9 : libxml2-2.9.13-2.el9

medium Nessus Plugin ID 191295

Language:

Synopsis

The remote CentOS host is missing a security update for libxml2.

Description

The remote CentOS Linux 9 host has packages installed that are affected by a vulnerability as referenced in the libxml2-2.9.13-2.el9 build changelog.

 - 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. (CVE-2022-29824)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the CentOS 9 Stream libxml2 package.
