"Sergey Gorbaty reported issues related to the FreeType font engine.
FreeType improperly handled certain malformed font files, allowing
remote attackers to cause a Denial of Service when specially crafted
font files were used.

For Debian 6 'Squeeze', these issues have been fixed in
freetype version 2.4.2-2.1+squeeze6. We recommend you to upgrade your
freetype packages.
