Synopsis
The remote Gentoo host is missing one or more security-related patches.Description
The remote host is affected by the vulnerability described in GLSA-201401-23 (sudo: Privilege escalation)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.
Solution
All sudo users should upgrade to the latest version:# emerge --sync # emerge --ask --oneshot --verbose '>=app-admin/sudo-1.8.6_p7'
