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)
