Synopsis ========
Multiple vulnerabilities have been found in sudo, the worst of which could result in privilege escalation.
Background ==========
sudo (su "do") allows a system administrator to delegate authority to give certain users (or groups of users) the ability to run some (or all) commands as root or another user while providing an audit trail of the commands and their arguments.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-admin/sudo < 1.9.5_p2 >= 1.9.5_p2
Description ===========
Multiple vulnerabilities have been discovered in sudo. Please review the CVE identifiers referenced below for details.
Impact ======
Local users are able to gain unauthorized privileges on the system or determine the existence of files.
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-1.9.5_p2"
