    Summary: libsecp256k1 allows overflowing signatures

    Details: libsecp256k1 accepts signatures whose R or S parameter is larger than the secp256k1 curve order, which differs from other implementations. This could lead to invalid signatures being verified. The error is resolved in 0.5.0 by adding a `check_overflow` flag.
