Vulnerability Note VU#931588
Ethereal fails to properly decode BGP packets containing MPLS IPv6 labels
Ethereal is a network traffic analysis package. It includes the ability to decode packets containing BGP data. According to RFC3031, an MPLS label is an identifier used to represent the Forwarding Equivalence Class (FEC) to which that packet is assigned. There is a buffer overflow vulnerability in the way the BGP protocol dissector decodes MPLS IPv6 labels.
According to the e-matters Security Advisory:
A remote, unauthenticated attacker could cause Ethereal to crash or potentially execute code of the attacker's choice.
2) Deselect the BGP protocol dissector from the list
(for Ethereal versions 0.10.x)
2) Disable the BGP protocol dissector from the list by unchecking its "Status" checkbox
However, it is strongly encouraged to upgrade to version 0.10.3 or later.
