Description Laura Pardo 2018-04-10 12:15:56 EDT

A flaw was found in Wireshark 2.4.0 to 2.4.5 and 2.2.0 to 2.2.13, the NBAP dissector could crash with a large loop that ends with a heap-based buffer overflow. This was addressed in epan/dissectors/packet-nbap.c by prohibiting the self-linking of DCH-IDs.
