Stack-based buffer overflow in ovutil.dll in HP OpenView Network Node Manager (OV NNM) 7.51 and 7.53 allows remote attackers to execute arbitrary code via a long COOKIE variable.
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.
