Description

The Array.prototype.concat implementation in builtins.cc in Google V8, as used in Google Chrome before 49.0.2623.108, does not properly consider element data types, which allows remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via crafted JavaScript code.
