The administration web interface in NetWin SurgeFTP 2.3a2 and earlier allows remote attackers to cause a denial of service (daemon crash) via a large integer in the Content-Length HTTP header, which triggers a NULL pointer dereference when memory allocation fails.
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.
