A vulnerability found in D-bus. This flaw allows an authenticated attacker to cause dbus-daemon and other programs that use libdbus to crash when receiving a message whose array length is inconsistent with the size of the element type.

It was discovered that DBus incorrectly handled messages with invalid type signatures. A local attacker could possibly use this issue to cause DBus to crash, resulting in a denial of service. It was discovered that DBus was incorrectly validating the length of arrays of fixed-length items. A local attacker could possibly use this issue to cause DBus to crash, resulting in a denial of service. It was discovered that DBus incorrectly handled the body DBus message with attached file descriptors. A local attacker could possibly use this issue to cause DBus to crash, resulting in a denial of service.
