TencentOS Server 4: libxml2 (TSSA-2024:0452)

high Nessus Plugin ID 239451

Synopsis

The remote TencentOS Server 4 host is missing one or more security updates.

Description

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the TSSA-2024:0452 advisory.

Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

CVE-2023-45322:
** DISPUTED ** 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.

Tenable has extracted the preceding description block directly from the Tencent Linux security advisory.

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.
