Regarding local versus remote, look at it this way: You have a 100% secure system.
There's no such thing.
Then you install NASM. Now a user FROM THE NETWORK can send you some tainted assembly code for you to assemble and he can compromise your account.
As has already been pointed out, a user from the network could send me a shell script containing "rm -rf ~". I'd be mad not to inspect a random unsolicited shell script before I ran it. I'd be mad not to inspect a similarly unsolicited NASM file before I assembled it; ditto input to csv2xml, abcm2ps, or many of the other "vulnerable" programs. This is not to belittle the effort that went into finding these bugs. Just to say that labelling them all as "remotely exploitable" is rather overstating the case.
