"This update for graphite2 fixes the following issues :

  - CVE-2016-1521: The directrun function in
    directmachine.cpp in Libgraphite did not validate a
    certain skip operation, which allowed remote attackers
    to execute arbitrary code, obtain sensitive information,
    or cause a denial of service (out-of-bounds read and
    application crash) via a crafted Graphite smart font.

  - CVE-2016-1523: The SillMap::readFace function in
    FeatureMap.cpp in Libgraphite mishandled a return value,
    which allowed remote attackers to cause a denial of
    service (missing initialization, NULL pointer
    dereference, and application crash) via a crafted
    Graphite smart font.

  - CVE-2016-1526: The TtfUtil:LocaLookup function in
    TtfUtil.cpp in Libgraphite incorrectly validated a size
    value, which allowed remote attackers to obtain
    sensitive information or cause a denial of service
    (out-of-bounds read and application crash) via a crafted
    Graphite smart font.

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
