WebKit in Apple Safari 4.x before 4.1.2 and 5.x before 5.0.2; Android before 2.2; and webkitgtk before 1.2.6; does not properly validate floating-point data, which allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted HTML document, related to non-standard NaN representation.

the problem is that the standard-library strtod()
parses "NAN(payload)" as a NaN with a user-defined payload, which is bad for the nan-boxing
scheme used by webkit (and mozilla). The fix is not to accept "NAN(payload)".
test-case: -parseFloat("NAN(ffffeeeeeff0f)")
reproduced with epiphany
