Incorrect Results In Exponentiation

gnark-crypto is vulnerable to Incorrect Results in Exponentiation. The vulnerability is due to the use of exponentiation à la GLV ExpGLV when the exponent exceeds the group order of the pairing target group GT. This sometimes results in incorrect outcomes compared to normal exponentiation Exp...

GHSA-PFFG-92CG-XF5C gnark-crypto's exponentiation in the pairing target group GT using GLV can give incorrect results

Impact When the exponent is bigger than r, the group order of the pairing target group GT, the exponentiation à la GLV ExpGLV can sometimes give incorrect results compared to normal exponentiation Exp. The issue impacts all users using ExpGLV for exponentiations in GT. This does not impact Exp an...
