Package : expat
Version : 2.2.6-2+deb10u5
CVE ID : CVE-2022-40674

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 Debian 10 buster, this problem has been fixed in version
2.2.6-2+deb10u5.

We recommend that you upgrade your expat packages.
