openSUSE 15 Security Update : libxml2 (SUSE-SU-2023:4464-1)

medium Nessus Plugin ID 185939

Language:

Synopsis

The remote openSUSE host is missing a security update.

Description

The remote openSUSE 15 host has a package installed that is affected by a vulnerability as referenced in the SUSE- SU-2023:4464-1 advisory.

- libxml2 through 2.11.5 has a use-after-free that can only occur after a certain memory allocation fails.
This occurs in xmlUnlinkNode in tree.c. NOTE: the vendor's position is I don't think these issues are critical enough to warrant a CVE ID ... because an attacker typically can't control when memory allocations fail. (CVE-2023-45322)

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 python3-libxml2-python package.
