Progea Movicon / PowerHMI 11.2.1085 and earlier allows remote attackers to cause a denial of service (memory corruption and crash) and possibly execute arbitrary code via an EIDP packet with a large size field, which writes a zero byte to an arbitrary memory location.
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.
