Synopsis :

The remote Ubuntu host is missing a security-related patch.

a user were tricked into using a specially crafted font file, a remote
attacker could cause t1lib to crash or possibly execute arbitrary code
with user privileges. (CVE-2010-2642, CVE-2011-0433)

Jonathan Brossard discovered that t1lib did not correctly handle
