CWE: CWE-190 \u2014 Integer Overflow or Wraparound
The product performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control.

Code:
int cp_bls_sig(g1_t s, const uint8_t *msg, size_t len, const bn_t d) {
	g1_t p;
	int result = RLC_OK;

	g1_null(p);

	RLC_TRY {
		g1_new(p);
		g1_map(p, msg, len);
		g1_mul_key(s, p, d);
	}
	RLC_CATCH_ANY {
		result = RLC_ERR;
	}
	RLC_FINALLY {
		g1_free(p);
	}
	return result;
}
