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-200902-01 (sudo: Privilege escalation)

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 :

A local attacker could possibly run commands as an arbitrary system user (including root).
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-1.7.0'
