"From Red Hat Security Advisory 2016:0594 :

An update for graphite2 is now available for Red Hat Enterprise Linux
7.

Red Hat Product Security has rated this update as having a security
impact of Important. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

Graphite2 is a project within SIL's Non-Roman Script Initiative and
Language Software Development groups to provide rendering capabilities
for complex non-Roman writing systems. Graphite can be used to create
'smart fonts' capable of displaying writing systems with various
complex behaviors. With respect to the Text Encoding Model, Graphite
handles the 'Rendering' aspect of writing system implementation.

The following packages have been upgraded to a newer upstream version:
graphite2 (1.3.6).

Security Fix(es) :

* Various vulnerabilities have been discovered in Graphite2. An
attacker able to trick an unsuspecting user into opening specially
crafted font files in an application using Graphite2 could exploit
these flaws to cause the application to crash or, potentially, execute
arbitrary code with the privileges of the application. (CVE-2016-1521,
CVE-2016-1522, CVE-2016-1523, CVE-2016-1526)"

    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

vulnerabilities :

  - Various vulnerabilities have been discovered in
    Graphite2. An attacker able to trick an unsuspecting
    user into opening specially crafted font files in an
    application using Graphite2 could exploit these flaws
    to cause the application to crash or, potentially,
    execute arbitrary code with the privileges of the
    application. (CVE-2016-1521, CVE-2016-1522,
    CVE-2016-1523, CVE-2016-1526)

Note that Tenable Network Security has extracted the preceding
description block directly from the EulerOS security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.");
