CentOS 9 : libxml2-2.9.13-5.el9

medium Nessus Plugin ID 193932

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 libxml2-2.9.13-5.el9 build changelog.

 - Xmlsoft Libxml2 v2.11.0 was discovered to contain an out-of-bounds read via the xmlSAX2StartElement() function at /libxml2/SAX2.c. This vulnerability allows attackers to cause a Denial of Service (DoS) via supplying a crafted XML file. NOTE: the vendor's position is that the product does not support the legacy SAX1 interface with custom callbacks; there is a crash even without crafted input. (CVE-2023-39615)

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.
