Description

Google V8, as used in Google Chrome before 34.0.1847.116, does not properly implement lazy deoptimization, which allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via crafted JavaScript code, as demonstrated by improper handling of a heap allocation of a number outside the Small Integer (aka smi) range.

Affected products

Google Chrome: through 34.0.1847.115
