| Severity: | high |
| Title: | sudo: Privilege escalation |
| Date: | 06/01/2010 |
| Bugs: | |
| ID: | 201006-09 |
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 | Architecture(s) |
|---|---|---|---|
| app-admin/sudo | < 1.7.2_p6 | >= 1.7.2_p6 | All supported architectures |
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"
