Debian DSA-5216-1 : libxslt - security update

high Nessus Plugin ID 164387

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

The remote Debian 11 host has packages installed that are affected by a vulnerability as referenced in the dsa-5216 advisory.

Nick Wellnhofer discovered that the xsltApplyTemplates function in libxslt, an XSLT processing runtime library, is prone to a use-after-free flaw, resulting in a denial of service, or potentially the execution of arbitrary code if a specially crafted file is processed. For the stable distribution (bullseye), this problem has been fixed in version 1.1.34-4+deb11u1. We recommend that you upgrade your libxslt packages.
For the detailed security status of libxslt please refer to its security tracker page at:
https://security-tracker.debian.org/tracker/libxslt

Tenable has extracted the preceding description block directly from the Debian 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

Upgrade the libxslt packages.

For the stable distribution (bullseye), this problem has been fixed in version 1.1.34-4+deb11u1.
