vxworks ftpd buffer overflow Denial of Service Vulnerability Scan

Vulnerability Scan Summary
Tries to CRASH VxWorks ftpd server with CEL overflow

Detailed Explanation for this Vulnerability Test

It was possible to make the remote host
crash by issuing this FTP command :

CEL aaaa(...)aaaa

This problem is similar to the 'aix ftpd' overflow
but on embedded vxworks based systems like the 3com
nbx IP phone call manager and seems to cause the server
to crash.

Solution: If you are using an embedded vxworks
product, please contact the OEM vendor and reference
WindRiver field patch TSR 296292. If this is the
3com NBX IP Phone call manager, contact 3com.

This affects VxWorks ftpd versions 5.4 and 5.4.2
