I haven't been following the chat room so I might have missed it, but
I'm surprised there hasn't been any discussion here about the
"denial of

I don't want to jump to conclusions, but we're talking about open
source
software here. He could have fixed it himself or at least filed a
Bugzilla report. As far as I can tell he did neither. He does claim to
have reported it to Apple. Is it in radar perhaps?
It is in Radar.
I don't recall ever getting proof of the "execute arbitrary code"
exploitability. We don't usually treat crashers as security bugs,
because then every reproducible crash would count as a security
exploit and that's not really reasonable given how many there are.
Can't comment on when/whether this will make it to a security update.
I'll wait before I say what I think about this guy. I don't want to be
slanderous without cause.
BTW I saw a claim elsewhere that it had been fixed in the
nightlies, but
it looks like as of a few minutes ago ensureRows in TOT still has the
problem (it does a resize with a value that doesn't appear to be
checked
against any limit).
We don't check against a hard limit but TOT will no longer crash or
overwrite memory (try it). We now detect the allocation failure. But
it might be good to also set a hard upper limit on rowspans.
