Re: [Discuss-gnuradio] UDP Source Error (on windows)

[mleech]

Not sure how this would get leveraged by itself.

But there are likely lots of kernel calls that have parameters that are ignored in certain contexts.  I would be astonished if a general-purpose, long-lived, operating existed without that being the case from time to time.

Easy enough to just remove that option for the UDP case.

I think it's a bit of a security failing of Linux to allow injection of
4 unused bytes into the kernel space from user-space for every locally
opened UDP socket.  I'm not sure how I could exploit it (perhaps coding
a jump instruction to a no-op sled somewhere nearby?),  but I'm not that
creative.

Meh.
