D-Bus is a system for sending messages between applications. It is used both for the system-wide message bus service, and as a per-user-login-session messaging facility.

Security Fix(es):

  • dbus: dbus-daemon crashes when receiving message with incorrectly nested parentheses and curly brackets (CVE-2022-42010)

  • dbus: dbus-daemon can be crashed by messages with array length inconsistent with element type (CVE-2022-42011)

  • dbus: _dbus_marshal_byteswap doesn’t process fds in messages with “foreign” endianness correctly (CVE-2022-42012)
