CBL Mariner 2.0 Security Update: libxml2 (CVE-2025-24928)

high Nessus Plugin ID 216892

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-2025-24928 advisory.

 - libxml2 before 2.12.10 and 2.13.x before 2.13.6 has a stack-based buffer overflow in xmlSnprintfElements in valid.c. To exploit this, DTD validation must occur for an untrusted document or untrusted DTD. NOTE:
 this is similar to CVE-2017-9047. (CVE-2025-24928)

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.
