epan/dissectors/packet-h225.c in the H.225 dissector in Wireshark 2.x before 2.0.6 calls snprintf with one of its input buffers as the output buffer, which allows remote attackers to cause a denial of service (copy overlap 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.
