Fixed In Version: xerces-c 3.1.3
Doc Type: Bug Fix
Doc Text:
It was discovered that the Xerces-C XML parser did not properly process certain XML input. By providing specially crafted XML data to an application using Xerces-C for XML processing, a remote attacker could exploit this flaw to cause an application crash or, possibly, execute arbitrary code with the privileges of the application.

Description Andrej Nemec 2016-02-26 08:10:58 UTC 
The Xerces-C XML parser mishandles certain kinds of malformed
input documents, resulting in buffer overlows during processing and error
reporting. The overflows can manifest as a segmentation fault or as memory
corruption during a parse operation. The bugs allow for a denial of service
attack in many applications by an unauthenticated attacker, and could
conceivably result in remote code execution.
