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.
(CVE-2016-2099)
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
16.04 ESM. (CVE-2016-4463)

CVE-2017-12627 [CRITICAL] CVE-2017-12627 xerces-c: Null pointer dereference while processing the path to DTD allows denial of service
CVE-2017-12627 xerces-c: Null pointer dereference while processing the path to DTD allows denial of service
The Xerces-C XML parser mishandles certain kinds of external DTD references, resulting in dereference of a NULL pointer while processing the path to the DTD. The bug allows for a denial of service attack in applications that allow DTD processing and do not prevent external DTD usage, and could conceivably result in remote code execution.
