RHSA-2006:0160 - Security Advisory

Topic

Updated tetex packages that fix several integer overflows are now available.

This update has been rated as having moderate security impact by the Red
Hat Security Response Team.

Description

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.
