New JPG vulnerability?
« on: September 29, 2004, 01:05:44 AM »
Hi all,

Are we protected against this new, terrible JPG vulnerability with Avast? I know it is not "in the wild" yet, but from what I read the vulnerability is on it's way to being a full-blown worm.

I found a link to a sample of an infected file if anyone is interested. Bitdefender Free picks it up on demand, but Avast Home does not with defs 0440-01 (unless I am not doing something right).

There is already a example of this exploit, and it has be exploited in the wild.  A sample had been submitted, but they have yet to update their definitions.

On september 14th, Microsoft has released a security patch for it. Visit Windows Update and install ALL security patches/updates.

I check for updates daily. I installed this so-called "patch" (probably one of the worst implementations of a Microsoft fix ever) as soon as it came out.

 However multiple third party apps also install dll's etc. that are prone to this vulnerability. This is why I rely on my AV to be my first line of defense. As opposed to other viruses, safe computing practices are irrelevant for this specific vulnerability.

There is nothing that I like better than "knocking m$" however this link might lead you to other programmes that might still be open to attacks after installing M$ updates.  Got to give them the credit for fixing this quite quickly   ;)

BitDefender Free V7 alerts:

C:\temp\virus-jpeg.zip=>possibleVirus.jpg is infected with Exploit.Win32.MS04-028.Gen

I *know* about the Microsoft patches and fixes but my question was fairly specific: Will Avast also be able to identify it in one of the new defs?

I believe XP users with SP2 dont have the Exploit.  :)

You're right not XP2 but, that doesn't protect any of the other programs mentioned, There is also a fix for Office if your running that.

Yes, they have  :'(
This was correctly after, by a specific MS patch  ;)
