Affected Packages:

libxslt

Vulnerable:

Yes

Security database references:

In Mitre's CVE dictionary: CVE-2021-30560.

More information:

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.
