   An update that fixes three vulnerabilities is now available.

Description:


   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.

   This update was imported from the SUSE:SLE-12:Update project.
