Overview
Affected versions of this package are vulnerable to Out-of-bounds Write via the JCE Cipher.doFinal() function in org/bouncycastle/jcajce/provider/BaseCipher when the same byte array is used for both input and output during native encrypt or decrypt operations. An attacker can cause data corruption by exploiting this behavior.
