D-Bus: Denial of service

D-Bus: Denial of service A local Denial of Service vulnerability was discovered in D-Bus. dbus 2020-12-23 2020-12-23 755392 local 1.12.20 1.12.20

D-Bus is a message bus system which processes can use to talk to each other.

It was discovered that D-Bus did not properly handle the situation when two usernames have the same numeric UID.

An attacker could possibly cause a Denial of Service condition or trigger other undefined behavior, possibly including incorrect authorization decisions.

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-1.12.20"
