Multiple vulnerabilities have been found in sudo which could result in privilege escalation.
|Package||app-admin/sudo on all architectures|
|Affected versions||< 1.8.6_p7|
|Unaffected versions||>= 1.8.6_p7|
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.
Multiple vulnerabilities have been found in sudo:
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.
There is no known workaround at this time.
All sudo users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-admin/sudo-1.8.6_p7"
