| Doc Text: |
A flaw was found in Bouncy Castle for Java. An attacker could exploit this vulnerability by providing a specially crafted input to the PKCS#8 / PBES2 decryptors. This input could specify an excessively high Key Derivation Function (KDF) cost, causing the decryptor to consume significant computational resources. This resource exhaustion can lead to a denial of service (DoS), making the affected system unresponsive or unavailable.
