GLSA-200805-03 : Multiple X11 terminals: Local privilege escalation

medium Nessus Plugin ID 32151

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-200805-03 (Multiple X11 terminals: Local privilege escalation)

 Bernhard R. Link discovered that RXVT opens a terminal on :0 if the '-display' option is not specified and the DISPLAY environment variable is not set. Further research by the Gentoo Security Team has shown that aterm, Eterm, Mrxvt, multi-aterm, rxvt-unicode, and wterm are also affected.
 Impact :

 A local attacker could exploit this vulnerability to hijack X11 terminals of other users.
 Workaround :

 There is no known workaround at this time.

Solution

All aterm users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=x11-terms/aterm-1.0.1-r1' All Eterm users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=x11-terms/eterm-0.9.4-r1' All Mrxvt users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=x11-terms/mrxvt-0.5.3-r2' All multi-aterm users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=x11-terms/multi-aterm-0.2.1-r1' All RXVT users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=x11-terms/rxvt-2.7.10-r4' All rxvt-unicode users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=x11-terms/rxvt-unicode-9.02-r1' All wterm users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=x11-terms/wterm-6.2.9-r3'
