|Gentoo Linux Security Advisory
Title: sudo: Privilege escalation (GLSA 201006-09)
Date: June 01, 2010
A flaw in sudo's -e option may allow local attackers to execute arbitrary
sudo allows a system administrator to give users the ability to run
commands as other users.
Vulnerable: < 1.7.2_p6
Unaffected: >= 1.7.2_p6
Architectures: All supported architectures
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"
