Pro-face WinGP PC Runtime 3.1.00 and earlier, and ProServr.exe in Pro-face Pro-Server EX 1.30.000 and earlier, allows remote attackers to cause a denial of service (unhandled exception and daemon crash) via a crafted packet with a certain opcode that triggers an invalid attempt to allocate a large amount of memory.
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.
