GLSA-201003-01 : sudo: Privilege escalation

medium Nessus Plugin ID 44971

Language:

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-201003-01 (sudo: Privilege escalation)

 Multiple vulnerabilities have been discovered in sudo:
 Glenn Waller and neonsignal reported that sudo does not properly handle access control of the 'sudoedit' pseudo-command (CVE-2010-0426).
 Harald Koenig reported that sudo does not properly set supplementary groups when using the 'runas_default' option (CVE-2010-0427).
 Impact :

 A local attacker with privileges to use 'sudoedit' or the privilege to execute commands with the 'runas_default' setting enabled could leverage these vulnerabilities to execute arbitrary code with elevated privileges.
 Workaround :

 CVE-2010-0426: Revoke all 'sudoedit' privileges, or use the full path to sudoedit. CVE-2010-0427: Remove all occurrences of the 'runas_default' setting.

Solution

All sudo users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=app-admin/sudo-1.7.2_p4'
