CyberRota Analysis

AI-Generated

Bouncy Castle for Java versions prior to 1.85, as well as certain LTS and FIPS versions, are vulnerable due to PKCS#8 / PBES2 decryptors improperly handling unbounded key derivation function (KDF) costs from input. This flaw could lead to excessive resource consumption, potentially resulting in denial-of-service conditions. Organizations using affected versions for cryptographic operations should prioritize remediation to mitigate risks associated with this vulnerability.
