(RHSA-2012:0467) 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 flaws were found in the way FreeType handled TrueType Font (TTF),
Glyph Bitmap Distribution Format (BDF), Windows .fnt and .fon, and
PostScript Type 1 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-2012-1134, CVE-2012-1136, CVE-2012-1142,
CVE-2012-1144)
