Integer overflow in api.cc in Google V8, as used in Google Chrome
before 34.0.1847.131 on Windows and OS X and before 34.0.1847.132 on
Linux, allows remote attackers to cause a denial of service or
possibly have unspecified other impact via a large length value.


A quick examination of the code in Fedora shows that it is likely affected although the upstream patches would require some massaging to apply.
