Summary

objects.cc in Google V8 before 5.0.71.32, as used in Google Chrome before 51.0.2704.63, does not properly restrict lazy deoptimization, which allows remote attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via crafted JavaScript code.
