epan/dissectors/packet-wcp.c in the WCP dissector in Wireshark 1.10.x before 1.10.13 and 1.12.x before 1.12.4 does not properly initialize a data structure, which allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted packet that is improperly handled during decompression.
