|Gentoo Linux Security Advisory
Title: sudo: Arbitrary command execution (GLSA 200506-22)
Date: June 23, 2005
A vulnerability in sudo may allow local users to elevate privileges.
sudo allows a system administrator to give users the ability to run commands as other users.
Vulnerable: < 1.6.8_p9
Unaffected: >= 1.6.8_p9
Architectures: All supported architectures
The sudoers file is used to define the actions sudo users are permitted to perform. Charles Morris discovered that a specific layout of the sudoers file could cause the results of an internal check to be clobbered, leaving sudo vulnerable to a race condition.
Successful exploitation would permit a local sudo user to execute arbitrary commands as another user.
Reorder the sudoers file using the visudo utility to ensure the 'ALL' pseudo-command precedes other command definitions.
All sudo users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=app-admin/sudo-1.6.8_p9"
