IP and MAC bundle cracked-vulnerability warning-the black bar safety net
The principle is as follows: MAC and IP bundling is on the server, then we think the scope of what should be? Of course, also only on the server on the client, but if I modify the Client IP, get on the server? If you have already thought about this, and that it has been the theory of the cracked...
CVE-2005-4714
CVE-2005-4714 : Concrete details exist in Connected documents. OpenVMPS (VLAN Management Policy Server) up to version 1.3 has a format string vulnerability in the vmps_log function. This allows remote attackers to execute arbitrary code on the affected host (impact described as possible code exec...

CVE-2005-4440
The 802.1q VLAN protocol allows remote attackers to bypass network segmentation and spoof VLAN traffic via a message with two 802.1q tags, which causes the second tag to be redirected from a downstream switch after the first tag has been stripped, as demonstrated by Yersinia, aka "double-tagging...
