In Wireshark 2.6.0, 2.4.0 to 2.4.6, and 2.2.0 to 2.2.14, the GSM A DTAP dissector could crash. This was addressed in epan/dissectors/packet-gsm_a_dtap.c by fixing an off-by-one error that caused a buffer overflow.
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.
