Multiple buffer overflows in Schneider Electric Modicon Quantum PLC allow remote attackers to cause a denial of service via malformed requests to the (1) FTP server or (2) HTTP server.
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.
