Multiple buffer overflows in runtime.cc in Google V8 before 3.22.24.7, as used in Google Chrome before 31.0.1650.63, allow remote attackers to cause a denial of service or possibly have unspecified other impact via vectors that trigger a large typed array, related to the (1) Runtime_TypedArrayInitialize and (2) Runtime_TypedArrayInitializeFromArrayLike functions.
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.
