CBL Mariner 2.0 Security Update: libxml2 (CVE-2023-45322)

medium Nessus Plugin ID 214798

Synopsis

The remote CBL Mariner host is missing one or more security updates.

Description

The version of libxml2 installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2023-45322 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 packages.
