Heap-based buffer overflow in RealNetworks RealPlayer before 17.0.4.61 on Windows, and Mac RealPlayer before 12.0.1.1738, allows remote attackers to execute arbitrary code via a long string in the TRACKID element of an RMP file, a different vulnerability than CVE-2013-7260.
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.
