An update that fixes four 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-2016-1522: Code.cpp in Libgraphite did not consider recursive load
calls during a size check, which allowed remote attackers to cause a
denial of service (heap-based buffer overflow) or possibly execute
arbitrary code 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.
