Name of the Vulnerable Software and Affected Versions Google V8 versions prior to 4.2.77.8 Google Chrome versions prior to 42.0.2311.90

Description The issue allows remote attackers to cause a denial of service or possibly have unspecified other impact via crafted JavaScript code that leverages "type confusion" in the check-elimination optimization. This is due to a problem in the ReduceTransitionElementsKind function in hydrogen-check-elimination.cc.

Recommendations For Google V8 versions prior to 4.2.77.8, update to version 4.2.77.8 or later. For Google Chrome versions prior to 42.0.2311.90, update to version 42.0.2311.90 or later. As a temporary workaround, consider restricting the execution of crafted JavaScript code to minimize the risk of exploitation.
