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
certain malformed font files. If a user were tricked into using a
specially crafted font file, a remote attacker could cause t1lib to
crash. (CVE-2011-1552, CVE-2011-1553, CVE-2011-1554).

description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
