Detail

Synopsis

A flaw in sudo's -e option may allow local attackers to execute arbitrary commands.

Background

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

Description

The command matching functionality does not properly handle when a file in the current working directory has the same name as a pseudo-command in the sudoers file and the PATH contains an entry for ".".

Impact

A local attacker with the permission to run sudoedit could, under certain circumstances, execute arbitrary commands as whichever user he has permission to run sudoedit as, typically root.

Workaround

There is no known workaround at this time.

Resolution

All sudo users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-admin/sudo-1.7.2_p6"

Id Description
63878 sudo sudoedit Command Matching Failure Privilege Escalation

sudo contains a flaw that may allow an attacker to gain access to unauthorized privileges. A user with privilege to execute the sudoedit pseudo-command can place a file with the same name in the current folder and get it executed by sudo, allowing a local attacker to gain execution of arbitrary code as a privileged user, normally root.
