New Hole in AOL Instant Messenger

By D. IAN HOPPER, AP Technology Writer

WASHINGTON (AP) - A security hole in AOL Time Warner’s Instant Messenger
program used by millions of people worldwide can let a hacker take full
control of a victim’s computer, according to security researchers and
the company.

An AOL spokesman said the problem will be fixed soon, and users won’t have
to download anything.

We have identified the issue and have developed a resolution that should be deployed in the next day or two,'' AOL's Andrew Weinstein said. To
our knowledge, this issue has not affected any users.’’

The problem affects the newest versions as well as many earlier iterations
of AOL’s Instant Messenger program. Only the Windows version is at risk -
Instant Messenger for Macintosh, Palm and other platforms are not.

Discovered by a loose team of international researchers called ‘w00w00,’
the hole is a ``buffer overflow,’’ like the problem recently found in
Microsoft’s Windows XP.

By sending a stream of junk messages to the program, a hacker can
overwhelm the software and make the victim’s computer run any commands the
hacker wants.

``You could do just about anything, (you could) delete files on the
computer or take over the machine,’’ w00w00 founder Matt Conover said.

Conover said w00w00 has over 30 active members from 14 states and nine
countries. Until AOL’s fix is released, Conover said, Instant
Messenger users should restrict incoming messages to friends on their
``Buddy List.’’

``It will at least keep someone from attacking you at random,’’ Conover
said, but it wouldn’t help if the attack code is added to a virus that
propagates without the victim’s knowledge. AOL said it has not given its
users any advice in the interim.

Conover said the group found the problem several weeks ago, but didn’t
contact AOL until after Christmas. The group didn’t get any response from
AOL through an e-mail during the holiday week, he said, so w00w00 released
details - and a program that takes advantage of it - to public security
mailing lists less than a week later.

The program released by w00w00 remotely shuts down a person’s Instant
Messenger program, but could be modified to do more sinister things.

That practice is under scrutiny by security professionals. While some
independent researchers argue for a ``full disclosure’’ policy and say
software vendors are trying to cover up their mistakes, many companies say
users are better protected if the company has time to react.

Russ Cooper, who moderates a popular security mailing list and works for
security firm TruSecure, said Conover’s actions are irresponsible.

I think it's better to provide details of the exploit and then let other people write the actual code,'' Cooper said. Unfortunately, these are
fundamentally naive people with a very childish view of the world.’’

Cooper said he let Conover send the information out through his mailing
list, but only did so after noticing it was released through other
channels as well.

Conover said w00w00 set a New Year’s deadline for sentimental reasons,
because it was the anniversary of the group’s last major security release.
He defended the disclosure of the attack program.

This is the approach that w00w00 has historically taken to the problem,'' he said. For us it means providing all the information we
have available to the security community.’’

AOL’s Weinstein said the company would have appreciated more warning.

``We’d encourage any software programmer that discovers a vulnerability to
bring it to our attention prior to releasing it,’’ Weinstein said.

The press is always late…

I truly dislike their take on security problems. I guess this happens to
coincide with my decision to pursue computer security full-time, just like
when I was getting started in 1994. Things changed, but my customers are
still waiting for a better solution package.

Just go to http://www.w00w00.org for full details on this problem :slight_smile:
