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

Medium Nessus Plugin ID 96414


The remote Gentoo host is missing one or more security-related patches.


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.


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