 Could Allow Remote Code Execution (2588516)

Dear Dan,

Impacket was at first a Pysmb copy/update from Core Security in order to
play with RPC. (look at the source)
They've done some work on pysmb library in order to implement DCE/RPC
functionality in this dinosaurus lib.
Saying that we should use Impacket in order to craft *raw* UDP packet
is definitively the dumbest thing I've heard today. Seriously. Anyone can
confirm that ? Mario ? Carlos ? ....

Anyways, This guy doesn't understand shit, talks a lot about shit he
doesn't know about, why would you even spend time reading his shit ?

This vulnerability is about sending a *huge fucking* stream of UDP packets
on a closed port in order to trigger a int overflow via a ref count.
Most of the people here didn't even understand what we are talking
about/dealing with.

Anyways, it's probably time for you to unsubscribe since you don't follow
and S-K's like secn3t@...il.com are trying to act like they know.

Yeah right, a UDP int overflow triggered via a refcount UDP overflow that
you can trigger with 1 single TCP (with the right ACK) packet is the way to
go.

This mailing list is getting gay, seriously.

Cheers,
Antony.
