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.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-admin/sudo < 1.7.2_p6 >= 1.7.2_p6
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"
References
==========
