Apache reports:
The Xerces-C XML parser fails to successfully parse a
DTD that is deeply nested, and this causes a stack overflow, which
makes a denial of service attack against many applications possible
by an unauthenticated attacker.
Also, CVE-2016-2099: Use-after-free vulnerability in
validators/DTD/DTDScanner.cpp in Apache Xerces C++ 3.1.3 and earlier
allows context-dependent attackers to have unspecified impact via an
invalid character in an XML document.
