AI-Generated

Bouncy Castle for Java versions prior to 1.85 and specific LTS and FIPS versions are vulnerable to a denial-of-service (DoS) attack due to inadequate iteration-count bounds in PKCS#12 MAC and bag-decryption key derivation functions. This vulnerability could allow an attacker to exploit the affected libraries, potentially leading to service disruptions. Organizations using these versions of Bouncy Castle should prioritize updates to mitigate the risk of DoS attacks.
