FreeBSD : libxslt -- multiple vulnerabilities (a96cd659-303e-11f0-94b5-54ee755069b5)

high Nessus Plugin ID 236769

Language:

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the a96cd659-303e-11f0-94b5-54ee755069b5 advisory.

xsltGetInheritedNsList in libxslt before 1.1.43 has a use-after-free issue related to exclusion of result prefixes.
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.

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

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

Solution

Update the affected packages.
