D-Bus: Denial of Service

D-Bus: Denial of Service A vulnerability has been found in D-Bus which allows a local user to cause a Denial of Service. d-bus August 22, 2013 August 22, 2013: 1 473190 local 1.6.12 1.6.12

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

D-Bus’ _dbus_printf_string_upper_bound() function crashes if it returns exactly 1024 bytes.

A local attacker could provide specially-crafted input to an application using D-Bus which would cause _dbus_printf_string_upper_bound() to return 1024 bytes and crash, causing a Denial of Service condition.

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-1.6.12"
