Red Hat Security Advisory 2011-1085-01 - A flaw was found in the way the FreeType font rendering engine processed certain PostScript Type 1 fonts. If a user loaded a specially-crafted font file with an application linked against FreeType, it could cause the application to crash or, possibly, execute arbitrary code with the privileges of the user running the application. Users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. The X server must be restarted for this update to take effect.

Apple Security Advisory 2011-07-15-2 - A buffer overflow exists in FreeType's handling of TrueType font files. Viewing a maliciously crafted PDF file may lead to an unexpected application termination or arbitrary code execution. A signedness issue exists in FreeType's handling of Type 1 fonts. Viewing a maliciously crafted PDF file may lead to an unexpected application termination or arbitrary code execution. An invalid type conversion issue exists in the use of IOMobileFrameBuffer queueing primitives, which may allow malicious code running as the user to gain system privileges.
