> DESCRIPTION:
> fRoGGz has reported a weakness in McAfee Anti-Virus scan engine,
> which can be exploited by malware to bypass certain scanning
> functionality.
> 
> For more information:
> SA17126
> 
> The weakness affects version 4.4.0 (database version 4602) when
> scanning malformed ".arj" archives. Other versions may also be
> affected.
> 
> NOTE: This is not an issue on client systems, as the malware is still
> detected upon execution by the desktop on-access scanner.
> 
> SOLUTION:
> Database version 4603 is able to detect some malformed ".arj"
> archives. Certain malformed ".arj" archives are still not detected.
> 
> Desktop on-access scanner should be used to ensure that the malware
> is detected upon extraction.
> 
> Filter all compressed file archives at border gateways if they are
> not required.
> 
> PROVIDED AND/OR DISCOVERED BY:
> fRoGGz, SecuBox Labs
