The remote host is missing updates announced in
advisory RHSA-2005:354.
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 CVE-2004-0888 and
CVE-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 CVE-2004-0803, CVE-2004-0804 and CVE-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.
