Description
The dissect_clnp function in epan/dissectors/packet-clnp.c in the CLNP dissector in Wireshark 1.6.x before 1.6.13 and 1.8.x before 1.8.5 does not properly manage an offset variable, which allows remote attackers to cause a denial of service (infinite loop or application crash) via a malformed packet.
