New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200501-31 (teTeX, pTeX, CSTeX: Multiple vulnerabilities)

teTeX, pTeX and CSTeX all make use of Xpdf code and may therefore be vulnerable to the various overflows that were discovered in Xpdf code (CAN-2004-0888, CAN-2004-0889, CAN-2004-1125 and CAN-2005-0064).
Furthermore, Javier Fernandez-Sanguino Pena discovered that the xdvizilla script does not handle temporary files correctly.
Impact :

An attacker could design a malicious input file which, when processed using one of the TeX distributions, could lead to the execution of arbitrary code. Furthermore, a local attacker could create symbolic links in the temporary files directory, pointing to a valid file somewhere on the filesystem. When xdvizilla is called, this would result in the file being overwritten with the rights of the user running the script.
Workaround :

There is no known workaround at this time.

Solution

All teTeX users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=app-text/tetex-2.0.2-r5' All CSTeX users should also upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=app-text/cstetex-2.0.2-r1' Finally, all pTeX users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=app-text/ptex-3.1.4-r2'
