GLSA-200603-02 : teTeX, pTeX, CSTeX: Multiple overflows in included XPdf code

medium Nessus Plugin ID 21000

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-200603-02 (teTeX, pTeX, CSTeX: Multiple overflows in included XPdf code)

 CSTeX, teTex, and pTeX include XPdf code to handle PDF files. This XPdf code is vulnerable to several heap overflows (GLSA 200512-08) as well as several buffer and integer overflows discovered by Chris Evans (CESA-2005-003).
 Impact :

 An attacker could entice a user to open a specially crafted PDF file with teTeX, pTeX or CSTeX, potentially resulting in the execution of arbitrary code with the rights of the user running the affected application.
 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-r8' All CSTeX users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=app-text/cstetex-2.0.2-r2' All pTeX users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=app-text/ptex-3.1.5-r1'
