It was discovered that xerces-c, a validating XML parser library for C++, did not correctly scan DTDs. The use-after-free vulnerability resulting from this issue would allow a remote attacker to leverage a specially crafted XML file in order to crash the application or potentially execute arbitrary code. Please note that the patch fixing this issue comes at the expense of a newly introduced memory leak. For the stable distribution (buster), this problem has been fixed in version 3.2.2+debian-1+deb10u1. We recommend that you upgrade your xerces-c packages. For the detailed security status of xerces-c please refer to its security tracker page at: https://security-tracker.debian.org/tracker/xerces-c
