Package : xerces-c
CVE ID : CVE-2018-1311
Debian Bug : 947431
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:
