Doc Text:
A flaw was found in Bouncy Castle for Java, including its LTS and FIPS variants. This vulnerability allows a remote attacker to trigger an Out-Of-Memory (OOM) error by providing specially crafted input during a definite-length read operation. This unbounded memory allocation can lead to a Denial of Service (DoS), making the affected system or application unavailable.
