This script is Copyright (C) 2014-2015 Tenable Network Security, Inc.


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-201406-27
(polkit, Spice-Gtk, systemd, HPLIP, libvirt: Privilege escalation)

polkit has a race condition which potentially allows a process to change
its UID/EUID via suid or pkexec before authentication is completed.

Impact :

A local attacker could start a suid or pkexec process through a
polkit-enabled application, which could result in privilege escalation or
bypass of polkit restrictions.

Workaround :

There is no known workaround at this time.

# emerge --sync
# emerge --ask --oneshot --verbose '>=sys-auth/polkit-0.112'
All HPLIP users should upgrade to the latest version:
