In Wireshark 2.6.0 to 2.6.1, 2.4.0 to 2.4.7, and 2.2.0 to 2.2.15, the BGP protocol dissector could go into a large loop. This was addressed in epan/dissectors/packet-bgp.c by validating Path Attribute lengths.
The product performs an iteration or loop without sufficiently limiting the number of times that the loop is executed.
