A vulnerability has been found in D-Bus possibly resulting in a local Denial of Service.
|Package||sys-apps/dbus on all architectures|
|Affected versions||< 1.10.12|
|Unaffected versions||>= 1.10.12|
D-Bus is a message bus system, a simple way for applications to talk to one another.
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.
A local attacker could cause a Denial of Service condition or possibly execute arbitrary code.
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"
