sudo: Privilege escalation

sudo: Privilege escalation Two vulnerabilities have been discovered in sudo, allowing local attackers to possibly gain escalated privileges. sudo March 06, 2012 March 06, 2012: 1 351490 401533 local 1.8.3_p2 1.7.4_p5 1.8.3_p2

sudo allows a system administrator to give users the ability to run commands as other users.

Two vulnerabilities have been discovered in sudo:

When the sudoers file is configured with a Runas group, sudo does not prompt for a password when changing to the new group (CVE-2011-0010).
A format string vulnerability exists in the "sudo_debug()" function (CVE-2012-0809).

A local attacker could possibly gain the ability to run arbitrary commands with the privileges of other users or groups, including root.

There is no known workaround at this time.

All sudo users should upgrade to the latest version:


      # emerge --sync
      # emerge --ask --oneshot --verbose ">=app-admin/sudo-1.8.3_p2"
