    Summary: Flaw in Scalar::check_overflow allows side-channel timing attack

    Details: Versions of `libsecp256k1` prior to `0.3.1` did not execute Scalar::check_overflow in constant time. This allows an attacker to potentially leak information via a timing attack. The flaw was corrected by modifying Scalar::check_overflow to execute in constant time.
