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

This script is Copyright (C) 2016 Tenable Network Security, Inc.


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.
