Synopsis ========
A vulnerability has been found in sudo allowing a local attacker to gain elevated privileges.
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 < 1.8.5 >= 1.8.5 < 1.6.9
Description ===========
When the Sudo env_reset option is disabled (it is enabled by default), certain environment variables are not blacklisted as expected.
Impact ======
A local attacker, authorized to run commands using sudo, can use this flaw to execute arbitrary code or escalate his privileges.
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-1.8.5"
