Updated xerces-c packages fix security vulnerabilities

Updated xerces-c packages fix security vulnerability: 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. 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 (CVE-2015-0252).
