A flaw in sudo's -e option may allow local attackers to execute arbitrary commands.
|Package||app-admin/sudo on all architectures|
|Affected versions||< 1.7.2_p6|
|Unaffected versions||>= 1.7.2_p6|
sudo allows a system administrator to give users the ability to run commands as other users.
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 ".".
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.
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-1.7.2_p6"
