The DehoistArrayIndex function in hydrogen-dehoist.cc (aka hydrogen.cc) in Google V8 before 3.22.24.7, as used in Google Chrome before 31.0.1650.63, allows remote attackers to cause a denial of service (out-of-bounds write) or possibly have unspecified other impact via JavaScript code that sets the value of an array element with a crafted index.
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.
