A vulnerability has been discovered and corrected in freetype2:

Multiple stack overflow flaws have been reported in the way FreeType
font rendering engine processed certain CFF opcodes. An attacker
could use these flaws to create a specially-crafted font file that,
when opened, would cause an application linked against libfreetype
to crash, or, possibly execute arbitrary code (CVE-2010-1797).

Packages for 2008.0 and 2009.0 are provided as of the Extended
