3. 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 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)
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.
(CVE-2012-1126, CVE-2012-1127, CVE-2012-1130, CVE-2012-1131, CVE-2012-1132,
CVE-2012-1137, CVE-2012-1139, CVE-2012-1140, CVE-2012-1141, CVE-2012-1143)
Red Hat would like to thank Mateusz Jurczyk of the Google Security Team for
reporting these issues.
Users are advised to upgrade to these updated packages, which contain a
backported patch to correct these issues. The X server must be restarted
(log out, then log back in) for this update to take effect.
