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.

Solution

All polkit users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=sys-auth/polkit-0.112' All HPLIP users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-print/hplip-3.14.1' All Spice-Gtk users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-misc/spice-gtk-0.21' All systemd users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=sys-apps/systemd-204-r1' All libvirt users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=app-emulation/libvirt-1.1.2-r3'
