IBM CICS Transaction Server 3.1, 3.2, 4.1, 4.2, and 5.1 on z/OS does not properly implement CEMT transactions, which allows remote authenticated users to cause a denial of service (storage overlay) by using a 3270 emulator to send an invalid 3270 data stream.
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.
