GLSA-201701-20 : D-Bus: Format string vulnerability

medium Nessus Plugin ID 96414

Language:

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-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 flaw.

Solution

All D-Bus users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=sys-apps/dbus-1.10.12'
