Package        : libxslt
CVE ID         : CVE-2021-30560

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.
