SubjectRe: [PATCH] Bluetooth: Prevent buffer overflow in l2cap config request
Hi Dan,

* Dan Rosenberg <drosenberg@vsecurity.com> [2011-06-24 08:38:05 -0400]:

> A remote user can provide a small value for the command size field in
> the command header of an l2cap configuration request, resulting in an
> integer underflow when subtracting the size of the configuration request
> header. This results in copying a very large amount of data via
> memcpy() and destroying the kernel heap. Check for underflow.
