Fedora Update Notification
FEDORA-2004-585
2005-01-03
---------------------------------------------------------------------

Product : Fedora Core 3
Name : tetex
Version : 2.0.2
Release : 21.2
Summary : The TeX text formatting system.
Description :
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. Usually, TeX is used in conjunction with a higher level formatting package like LaTeX or PlainTeX, since TeX by itself is not very user-friendly.

Install tetex if you want to use the TeX text formatting system. If you are installing tetex, you will also need to install tetex-afm (a PostScript(TM) font converter for TeX), tetex-dvips (for converting .dvi files to PostScript format
for printing on PostScript printers), tetex-latex (a higher level formatting package which provides an easier-to-use interface for TeX), and tetex-xdvi (for previewing .dvi files in X). Unless you are an expert at using TeX, you should also install the tetex-doc package, which includes the documentation for TeX.

---------------------------------------------------------------------
Update Information:

The updated tetex package fixes a buffer overflow which allows attackers to cause the internal xpdf library used by applications in tetex to crash, and possibly to execute arbitrary code. The Common Vulnerabilities and Exposures projects (cve.mitre.org) has assigned the name CAN-2004-1125
to this issue.
