Description :

The remote host is affected by the vulnerability described in GLSA-201701-20
(D-Bus: Format string vulnerability)

It was discovered that D-Bus incorrectly handles certain format strings.
The impact of this new vulnerability is believed to not be exploitable
if D-Bus is patched against CVE-2015-0245. The previous vulnerability
(CVE-2015-0245) was addressed in GLSA-201503-02 referenced below.

Impact :

A local attacker could cause a Denial of Service condition or possibly
execute arbitrary code.

Workaround :

The vulnerable D-Bus interface is intended only for use by systemd
running as root.
The administrator can install a policy which denies sending from
org.freedesktop.systemd1.Activator” to D-Bus. This will prevent
non-root attackers from reaching the interface in order to exercise this

Solution :

# emerge --sync
# emerge --ask --oneshot --verbose '>=sys-apps/dbus-1.10.12'
