Heap-based buffer overflow in the NTLM authentication functionality in RealNetworks Helix Server and Helix Mobile Server 11.x, 12.x, and 13.x allows remote attackers to have an unspecified impact via invalid base64-encoded data.
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.
