Fedora Core 3: 2004-585 Critical: Tetex Buffer Overflow Exploit

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.

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.
