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"
