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-5236 advisory.

Rhodri James discovered a heap use-after-free vulnerability in the doContent function in Expat, an XML parsing C library, which could result in denial of service or potentially the execution of arbitrary code, if a malformed XML file is processed. For the stable distribution (bullseye), this problem has been fixed in version 2.2.10-2+deb11u4. We recommend that you upgrade your expat packages. For the detailed security status of expat please refer to its security tracker page at: https://security- tracker.debian.org/tracker/expat

For the stable distribution (bullseye), this problem has been fixed in version 2.2.10-2+deb11u4.
