xerces-c

Vulnerable:

Yes

Security database references:

In the Debian bugtracking system: Bug 947431.
In Mitre's CVE dictionary: CVE-2018-1311.

More information:

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.
