   An update that solves two vulnerabilities and has one
   errata is now available.

Description:


   This update for expat fixes the following security issues:

   - CVE-2012-6702: Expat, when used in a parser that has not called
     XML_SetHashSalt or passed it a seed of 0, made it easier for
     context-dependent attackers to defeat cryptographic protection
     mechanisms via vectors involving use of the srand function.  (bsc#983215)
   - CVE-2016-5300: The XML parser in Expat did not use sufficient entropy
     for hash initialization, which allowed context-dependent attackers to
     cause a denial of service (CPU consumption) via crafted identifiers in
     an XML document. NOTE: this vulnerability exists because of an
     incomplete fix for CVE-2012-0876.  (bsc#983216)
