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.
Upgrade to version 0.10.3 or later.
Ethereal credits Stefan Esser for reporting this vulnerability.
