An update that solves two vulnerabilities and has one security fix can now be installed.

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)
