"Anton Rager and Jonathan Brossard from the Salesforce.com Product
Security Team and Ben Laurie of Google discovered a denial of service
vulnerability in xerces-c, a validating XML parser library for C++.
The parser mishandles certain kinds of malformed input documents,
resulting in a segmentation fault during a parse operation. An
unauthenticated attacker could use this flaw to cause an application
using the xerces-c library to crash.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
