Heap-based buffer overflow in the embedded player in multiple RealNetworks products and versions including RealPlayer 10.x, RealOne Player, and Helix Player allows remote malicious servers to cause a denial of service (crash) and possibly execute arbitrary code via a chunked Transfer-Encoding HTTP response in which either (1) the chunk header length is specified as -1, (2) the chunk header with a length that is less than the actual amount of sent data, or (3) a missing chunk header.
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.
