Several vulnerabilities have been discovered in Expat, an XML parsing C

execution of arbitrary code, if a malformed XML file is processed.

For the oldstable distribution (buster), these problems have been fixed
in version 2.2.6-2+deb10u3.

For the stable distribution (bullseye), these problems have been fixed in
