(RHSA-2006:0160) tetex security update

TeTeX is an implementation of TeX. TeX takes a text file and a set of
formatting commands as input and creates a typesetter-independent .dvi
(DeVice Independent) file as output.

Several flaws were discovered in the teTeX PDF parsing library. An attacker
could construct a carefully crafted PDF file that could cause teTeX to
crash or possibly execute arbitrary code when opened. The Common
Vulnerabilities and Exposures project assigned the names CVE-2005-3191,
CVE-2005-3192, CVE-2005-3193, CVE-2005-3624, CVE-2005-3625, CVE-2005-3626,
CVE-2005-3627 and CVE-2005-3628 to these issues.

Users of teTeX should upgrade to these updated packages, which contain
backported patches and are not vulnerable to these issues.
