AlmaLinux 9 : libxml2 (ALSA-2023:7747)

medium Nessus Plugin ID 186918

Synopsis

The remote AlmaLinux host is missing a security update.

Description

The remote AlmaLinux 9 host has packages installed that are affected by a vulnerability as referenced in the ALSA-2023:7747 advisory.

 - 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 affected libxml2, libxml2-devel and / or python3-libxml2 packages.
