In Mitre's CVE dictionary: CVE-2016-0718, CVE-2016-4472.
More information:

Gustavo Grieco discovered that Expat, an XML parsing C library, does not properly handle certain kinds of malformed input documents, resulting in buffer overflows during processing and error reporting. A remote attacker can take advantage of this flaw to cause an application using the Expat library to crash, or potentially, to execute arbitrary code with the privileges of the user running the application.

For the stable distribution (jessie), this problem has been fixed in version 2.1.0-6+deb8u2. Additionally this update refreshes the fix for CVE-2015-1283 to avoid relying on undefined behavior.

We recommend that you upgrade your expat packages.
