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.
