Description

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.
