A vulnerability has been found in sudo allowing a local attacker to gain elevated privileges.
|Package||app-admin/sudo on all architectures|
|Affected versions||< 1.8.5|
|Unaffected versions||>= 1.8.5
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.
When the Sudo env_reset option is disabled (it is enabled by default), certain environment variables are not blacklisted as expected.
A local attacker, authorized to run commands using sudo, can use this flaw to execute arbitrary code or escalate his privileges.
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-1.8.5"
