CVE-2014-9490: sentry-raven allows remote attackers to cause a denial of service via a large exponent value in a scientific number

The vulnerability stems from the numtok() function's handling of scientific notation in JSON parsing. The original code converted exponents by performing 10^N computations, which becomes computationally expensive for large N values. The patch explicitly removes this computation and returns the raw string instead. The CVE description, commit diff, and test case changes all directly implicate this function as the vulnerable component.
