Description

Updated tetex packages that fix a security issue in PDF handling are now available for CentOS Linux 2.1, 3, 4, and 5. This update has been rated as having important security impact by the Red Hat Security Response Team.

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. Maurycy Prodeus discovered an integer overflow flaw in the processing of PDF files. An attacker could create a malicious PDF file that would cause TeTeX to crash or potentially execute arbitrary code when opened. (CVE-2007-3387) All users of TeTeX should upgrade to these updated packages, which contain a backported patch to resolve this issue.
