Description
epan/proto.c in Wireshark 1.12.x before 1.12.4 does not properly handle integer data types greater than 32 bits in size, which allows remote attackers to cause a denial of service (assertion failure and application exit) via a crafted packet that is improperly handled by the LLDP dissector.
