Security Fix(es):

  * A stack buffer overflow flaw was found in the way the Bluetooth subsystem
of the Linux kernel processed pending L2CAP configuration responses from a
client. On systems with the stack protection feature enabled in the kernel
(CONFIG_CC_STACKPROTECTOR=y, which is enabled on all architectures other
than s390x and ppc64[le]), an unauthenticated attacker able to initiate a
connection to a system via Bluetooth could use this flaw to crash the
system. Due to the nature of the stack protection feature, code execution
cannot be fully ruled out, although we believe it is unlikely. On systems
without the stack protection feature (ppc64[le]  the Bluetooth modules are
not built on s390x), an unauthenticated attacker able to initiate a
connection to a system via Bluetooth could use this flaw to remotely
execute arbitrary code on the system with ring 0 (kernel) privileges.
