Details

Pierre Betouin discovered a Denial of Service vulnerability in the
handling of the L2CAP (Logical Link Control and Adaptation Layer
Protocol) layer. By sending a specially crafted L2CAP packet through a
wireless Bluetooth connection, a remote attacker could crash hcidump.

Since hcidump is mainly a debugging tool, the impact of this flaw is
very low.
