Multiple Antivirus Scanners DoS attack.

--- [Vulnerable Products] ---

           Only tested on...

* Norton Antivirus 2002
* Norton Antivirus 2003

* Mcafee VirusScan 6 
* Network Associates (McAfee) VirusScan Enterprise 7.1

* F-Prot 4.4.2 for Linux

* Rav Antivirus online Scanner [Couldn't complete the
scan...]

* Windows Xp default ZIP manager [report's wrong size
of compress ZIP files.]

Risk Impact: Medium

--- [Details] ---
While having a manual scan of compressed files;
several Antivirus, Trojan, Spy ware scanners suffer a
DoS attack if the software tries to completely extract
the archive and scan its content for a hostile file.

--- [Proof of Concept] ---

Please download this file.

Moreover it's not safe to set automatically
'Quarantine/delete' option set for your AV scanner as
it may try to Quarantine the virus by extracting the
archive.
