SUSE SLED12 / SLES12 Security Update : graphite2 (SUSE-SU-2016:0779-1)

Medium Nessus Plugin ID 89991

Synopsis

The remote SUSE host is missing one or more security updates.

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.

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.
