RHSA-2015:0696 - Security Advisory

Topic

Updated freetype packages that fix multiple security issues are now
available for Red Hat Enterprise Linux 6 and 7.

Red Hat Product Security has rated this update as having Important security
impact. Common Vulnerability Scoring System (CVSS) base scores, which give
detailed severity ratings, are available for each vulnerability from the
CVE links in the References section.

Description

FreeType is a free, high-quality, portable font engine that can open and
manage font files. It also loads, hints, and renders individual glyphs
efficiently.

Multiple integer overflow flaws and an integer signedness flaw, leading to
heap-based buffer overflows, were found in the way FreeType handled Mac
fonts. If a specially crafted font file was loaded by an application linked
against FreeType, it could cause the application to crash or, potentially,
execute arbitrary code with the privileges of the user running the
application. (CVE-2014-9673, CVE-2014-9674)

Multiple flaws were found in the way FreeType handled fonts in various
formats. If a specially crafted font file was loaded by an application
linked against FreeType, it could cause the application to crash or,
possibly, disclose a portion of the application memory. (CVE-2014-9657,
CVE-2014-9658, CVE-2014-9660, CVE-2014-9661, CVE-2014-9663, CVE-2014-9664,
CVE-2014-9667, CVE-2014-9669, CVE-2014-9670, CVE-2014-9671, CVE-2014-9675)

All freetype users are advised to upgrade to these updated packages, which
contain backported patches to correct these issues. The X server must be
restarted (log out, then log back in) for this update to take effect.
