Vulnerability Assessment Details
Check for the version of the tetex package
Detailed Explanation for this Vulnerability Assessment
The remote host is missing the patch for the advisory FEDORA-2005-1127 (tetex).
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
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.
Several flaws were discovered in Xpdf. A possible hacker could
construct a carefully crafted PDF file that could cause Xpdf
to crash or possibly execute arbitrary code when opened. The
teTeX package contains a copy of the Xpdf code used for
parsing PDF files and is therefore affected by this bug.The
Common Vulnerabilities and Exposures project assigned the
name CAN-2005-3193 to these issues.
Users of teTeX should upgrade to this updated package, which
contains a patch to resolve these issues.
