<title>sudo: Privilege escalation</title>
A vulnerability in sudo may allow for privilege escalation.

sudo allows a system administrator to give users the ability to run
commands as other users.
Harald Koenig discovered that sudo incorrectly handles group
specifications in Runas_Alias (and related) entries when a group is
specified in the list (using %group syntax, to allow a user to run
commands as any member of that group) and the user is already a member
of that group.
<impact type="high">
A local attacker could possibly run commands as an arbitrary system
user (including root).
There is no known workaround at this time.
All sudo users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=app-admin/sudo-1.7.0&quot;</code>
