epan/dissectors/packet-gsm_cbch.c in the GSM CBCH dissector in Wireshark 1.12.x before 1.12.11 and 2.0.x before 2.0.3 uses the wrong variable to index an array, which allows remote attackers to cause a denial of service (out-of-bounds access and application crash) via a crafted packet.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
