No. I tried it with both FreeBSD's uudecode and GNU's
uudecode from
sharutils-4.2. The killer jpeg causes uudecode to exit immediately with
an error. My FreeBSD uudecode reports:
uudecode: stdin: illegal ~user
So on a hunch, I replaced my uudecode with:
#!/bin/sh
exit 0
I immediately got a crash.
That would be positive ...
But I just tried it three more times and I didn't.
... but that isn't.
I know I'm stating the obvious, but I guess it's a race
condition.
Yes, that is likely. The code says there's a SIGPIPE handler
installed, but somehow it sometimes isn't. In my case, the killer
jpeg is a sure kill.
This bug isn't new. It's been around for a long time -- at least back
to 20.3, I think.
Come to think of it, after my initial crash, I did a netstat -t and
I
noticed that I didn't have a connection to the news server. I didn't
think much about it at the time.
