An incorrect arithmetic operation when processing VLAN Virtual Local Area Network header bits in double-tagged packets can lead to a heap-buffer-overflow. A local attacker could exploit this ...

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...
