(RHSA-2012:0094) Important: freetype security update

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 input validation flaws were found in the way FreeType processed
bitmap font files. 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-2011-3256)

Multiple input validation flaws were found in the way FreeType processed
CID-keyed 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-2011-3439)

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.
