Hi malware fighters,

While trying to place a downloaded pdf file into a folder, avast warned me for sign of “CVE-2007-3896 ;Expl] J”, see: http://nvd.nist.gov/nvd.cfm?cvename=CVE-2007-3896
I placed the file into the chest. I already updated to the latest known version of Adobe.
What more should I do? These Uri-handler problems with IE7 are driving me nuts, time for M$ to come up with a real solution, and not to blame it on other software that implement their crap.
Good thing avast save my glorious behind again. Thanks avast.

It is nice to see that avast has a detection for this, though I’m not sure if it might not be an FP.

I would have though that this would have been something like a web shield detection coming from a modified URL to call the other application, rather than downloading it and only when it was put in a folder did it alert.

I’m not sure this exploit is actually in a pdf file, rather on the web page URL ?
Probably worth a visit to VirusTotal - Multi engine on-line virus scanner and confirm the detection. You can’t do this with the file in the chest, you will need to move it out (export).

Hi DavidR,

Funny you say that because that crossed my mind as well - FP. Because why did not avast alarm when I downloaded it, but roars at me touching the bastard? Anyways cannot do any harm in the chest, and later I can do an online check on the files perimeters of the download.
I do not like it but occasionally when avast turns its head, I think “oh it is still doing its job”…

Ta,

Whilst it can’t do any harm in the chest I like to confirm detections and I don’t feel comfortable until I have that done.

If an FP exists submit the sample so it doesn’t potentially effect others.

Polonus, please send the sample directly to me. I’d like to check if there may be FP, the method I used in the detection is quite generic.
