high Nessus Plugin ID 233336

Synopsis

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

Description

The version of libxslt 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-2025-24855 advisory.

 - numbers.c in libxslt before 1.1.43 has a use-after-free because, in nested XPath evaluations, an XPath context node can be modified but never restored. This is related to xsltNumberFormatGetValue, xsltEvalXPathPredicate, xsltEvalXPathStringNs, and xsltComputeSortResultInternal. (CVE-2025-24855)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
