This security bulletin contains one low risk vulnerability.
The vulnerability allows a remote attacker to disclose sensitive information.
The vulnerability exists in Bouncy Castle JCE Provider due to buggy implementation of squaring for several raw math classes have been fixed (org.bouncycastle.math.raw.Nat???). These classes are used by our custom elliptic curve implementations (org.bouncycastle.math.ec.custom.**), so there was the possibility of rare (in general usage) spurious calculations for elliptic curve scalar multiplications. Such errors would have been detected with high probability by the output validation for our scalar multipliers.Mitigation
