An authentication bypass was discovered in D-Bus.
|Package||sys-apps/dbus on all architectures|
|Affected versions||< 1.12.16|
|Unaffected versions||>= 1.12.16|
D-Bus is a message bus system which processes can use to talk to each other.
It was discovered that a local attacker could manipulate symbolic links in their own home directory to bypass authentication and connect to a DBusServer with elevated privileges.
A local attacker can bypass authentication mechanisms and elevate privileges.
There is no known workaround at this time.
All D-Bus users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=sys-apps/dbus-1.12.16"
