µTorrent exploit revealed

(Click here to view the original thread with full colors/images)




Posted by: torrentslave

http://www.zeropaid.com/bbs/../news/upload/images/thumb/8400.jpgAccording to IT security experts, the latest version of uTorrent is vulnerable to remote exploits.

Today brings news that the popular BitTorrent client server uTorrent (http://www.zeropaid.com/bbs/../news/6184/uTorrent+-+A+Beginner%27s+guide+to+BitTorrent+downloading) is vulnerable to hackers that can infiltrate your PC and execute arbitr ary code if a user opens a manipulated torrent tracker file.

The apparent "glitch" in the software is that torrent tracker fields may contain an "announce" field. Well, if this "announce" field is longer than 4800 bytes, an internal µTorrent (http://www.zeropaid.com/bbs/../news/6184/uTorrent+-+A+Beginner%27s+guide+to+BitTorrent+downloading) buffer overflows, thereby allowing hackers to run their exploits.

For now it's only µTorrent 1.6 build 474 that is affected but, older versions may also contain the bug, and a new version to fix the problem is not yet available.

Apparently works on XP SP1 and w2k sp1-4



Posted by: gamer4eva

Well it only affects those with announce higher than 4800bytes whatever that means.....



Posted by: Acidice

Heh, and with this, uT does downhill ........

Utorrent began to go downhill when it sold out....:lol:



Posted by: torrentslave

yep sucks big harry balls!!!!



Posted by: DefX

this is very upsetting. what are good alternatives out there aside from azureus? Something that doesnt consume lots of RAM.



Posted by: Alien5

wait for the fix.



Posted by: Jaits

the tracker owners can perform the fix in the tracker to not allow the faulty torrent to be uploaded.... u shouldnt really be opening torrents that other ppl send u anyhow...

the current shellcode doesnt affect sp2 so most users will be safe....

..........Safe? The only sharing that is safe, is the hand to hand sharing.

LOL

this shouldn't be a problem if you get your torrents from legit sites



Posted by: nebcat

Oh my god! Switching...Thanks for the heads up!



Posted by: erRor67

The latest beta fixes this problem.



Posted by: ewerest

"it only affects those with announce higher than 4800bytes"
and this kind of .torrent files are produced by porposely to hack you.so in the private trackers there is no need to worry about.



Posted by: Sentient

Heh, and with this, uT does downhill ........

Jesus, there's overreacting and then there's you guys. It doesn't even affect the latest build.



Posted by: S!X

ah excellent news.. they need a new final build in the works asap...



Posted by: 4play

It really should be a simple fix for this. Im just wondering why there isnt a new version out already.



Posted by: vipdiablo

yep sucks



Posted by: biggrizz

This is a bit worrying.I hope something is done soon



Posted by: Appzalien

I'd heard that some devious character took over the utorrent servers and I remember commenting to the poster and replyers that it didn't matter because utorrent didn't automatically update itself, you would have to download a new version created by this new owner to be vulnerable. And as long as you remained at the last version before he took over you should be ok.

Now that I hear utorrent itself warning customers that "if you know whats good for you you better update" I'm skeptical that a hole even exists. If the posters from before were indeed right, and this guy is devious, then this warning sounds devious as well. I don't know which is worse using an app with a security hole that has never been exploited (although it probably will be now!) or updating to a new version perhaps created with the mpaa and riaa's blessing for all I know.

The third option seems best to me, dump utorrent and use a different p2p client.

That's one of the best examples of "brain-FUD" I think I've ever seen. Congrats ! ;)
To believe or not to believe that is the question. ;)
If it's all the same with you, I think I'll upgrade anywayz ! ;)

Yes, its a final build. Download it here: http://download.utorrent.com/1.6.1/utorrent.exe

And just so you guys know, this exploit was fixed in a beta build back in July 2006. ;)

stole the quote....

yep, exactly. probably why i'll be installing azureus again anyhow. as, i've not yet intalled this "new" version of utorrent and i mite not.

This exploit is officially fixed in 1.6.1 build 489, released yesterday.

As erRor67 says, rumour is that it was actually fixed (as a tidying of the code) in the initial release of the Beta back in July 2006, but they hadn't thought of it as a vulnerability so it wasn't mentioned until now.

I've been using the Beta since then and I'm very happy with it, the changes in this final release are minimal and nothing to do with the sellout to bittorrent.



Posted by: Chip Monk

Cheers for the info, lynx.

Is it best to remove an older version then do a fresh install or is it OK to just download the installer and run it.

You can backup the the settings in the docs&settings/applicationdata/utorrent

how do u know?



Posted by: Hairbautt

At nsane:

So, safe to use after µtorrent joinup with bittorrent?

Bittorrent, Inc bought the right to use uTorrent's core. They do not own uTorrent, or have any power to interfere with the development.

I just keep checking to see if anyone has problems, so far none.

HAS anyone had any problems with Utorrent?

I just replaced my .exe file in the installation directory since this version doesn't have an installer.
