Severity: High Title: sudo: Privilege escalation Date: January 21, 2014 Bugs: #459722 ID: 201401-23

Synopsis ========
Multiple vulnerabilities have been found in sudo which could result in privilege escalation.
Background ==========
sudo allows a system administrator to give users the ability to run commands as other users. Access to commands may also be granted on a range to hosts.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-admin/sudo < 1.8.6_p7 >= 1.8.6_p7
Description ===========
Multiple vulnerabilities have been found in sudo:
* sudo does not correctly validate the controlling terminal on a system without /proc or when the tty_tickets option is enabled. * sudo does not properly handle the clock when it is set to the epoch.
Impact ======
A local attacker with sudo privileges could connect to the stdin, stdout, and stderr of the terminal of a user who has authenticated with sudo, allowing the attacker to hijack the authorization of the other user. Additionally, a local or physically proximate attacker could set the system clock to the epoch, bypassing time restrictions on sudo authentication.
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-1.8.6_p7"
