    An update that fixes two vulnerabilities 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)
