Fix BigInt exponentiation bypassing execution constraints by lahma · Pull Request #2350 · sebastienros/jint (original) (raw)
Validate estimated result size before calling BigInteger.Pow to prevent
memory exhaustion from inputs like 11n**711111111n. Limits result to
1 million bits (125 KB), throwing RangeError for excessive sizes.
Also fixes missing negative exponent check in **= assignment operator.
