CVE-2016-2099 [CRITICAL] Xerces-C++ vulnerabilities
Title: Xerces-C++ vulnerabilities
Summary: Several security issues were fixed in Xerces-C++.
It was discovered that Xerces-C++ XML Parser mishandles certain kinds of
external DTD references, resulting in a user-after-free. An attacker could
use this vulnerability to cause a denial of service (crash) or possibly
execute arbitrary code. This issue affected only Ubuntu 16.04 ESM.

It was discovered that Xerces-C++ XML Parser fails to successfully parse a
DTD that is too deeply nested. An unauthenticated attacker could use this
vulnerability to cause a denial of service. This issue affected only Ubuntu

CVE-2016-4463 [HIGH] CWE-121 xerces-c: Stack overflow when parsing deeply nested DTD
xerces-c: Stack overflow when parsing deeply nested DTD
Stack-based buffer overflow in Apache Xerces-C++ before 3.1.4 allows context-dependent attackers to cause a denial of service via a deeply nested DTD.
A stack exhaustion flaw was found in the way Xerces-C XML parser handled deeply nested DTDs. An attacker could potentially use this flaw to crash an application using Xerces-C by tricking it into processing specially crafted data.
Statement: Red Hat Product Security has rated this issue as having Moderate security impact. This issue is not currently planned to be addressed in future updates.

CVE-2016-4463 xerces-c: Stack overflow when parsing deeply nested DTD
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.
Upstream patch:

Upstream bugs:
https://issues.apache.org/jira/browse/XERCESC-2066
https://issues.apache.org/jira/browse/XERCESC-2069
In addition, a related enhancement was made to enable applications to fully disable DTD processing through the use of an environment variable.
