Description

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.

TeTeX is an implementation of TeX for Linux or UNIX systems. TeX takes a text file and a set of formatting commands as input and creates a typesetter-independent .dvi (DeVice Independent) file as output. A number of security flaws have been found affecting libraries used internally within teTeX. An attacker who has the ability to trick a user into processing a malicious file with teTeX could cause teTeX to crash or possibly execute arbitrary code. A number of integer overflow bugs that affect Xpdf were discovered. The teTeX package contains a copy of the Xpdf code used for parsing PDF files and is therefore affected by these bugs. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CAN-2004-0888 and CAN-2004-1125 to these issues. A number of integer overflow bugs that affect libtiff were discovered. The teTeX package contains an internal copy of libtiff used for parsing TIFF image files and is therefore affected by these bugs. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CAN-2004-0803, CAN-2004-0804 and CAN-2004-0886 to these issues. Also latex2html is added to package tetex-latex for 64bit platforms. Users of teTeX should upgrade to these updated packages, which contain backported patches and are not vulnerable to these issues.
