Description :

From Red Hat Security Advisory 2015:0696 :

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

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.
