Synopsis ========
A vulnerability in sudo may allow local users to elevate privileges.
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 < 1.6.8_p9 >= 1.6.8_p9
Description ===========
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.
Impact ======
Successful exploitation would permit a local sudo user to execute arbitrary commands as another user.
Workaround ==========
Reorder the sudoers file using the visudo utility to ensure the 'ALL' pseudo-command precedes other command definitions.
Resolution ==========
All sudo users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-admin/sudo-1.6.8_p9"
