Package        : xerces-c
CVE ID         : CVE-2016-4463
Debian Bug     : 828990

Brandon Perry discovered that xerces-c, a validating XML parser library
for C++, fails to successfully parse a DTD that is deeply nested,
causing a stack overflow. A remote unauthenticated attacker can take
advantage of this flaw to cause a denial of service against applications
using the xerces-c library.

Additionally this update includes an enhancement to enable applications
to fully disable DTD processing through the use of an environment
variable (XERCES_DISABLE_DTD).

For the stable distribution (jessie), this problem has been fixed in
version 3.1.1-5.1+deb8u3.

We recommend that you upgrade your xerces-c packages.
