The Bouncy Castle library for Java prior to version 1.85 is vulnerable due to an improper bounds check in the MLS wire decoder, allowing attackers to influence memory allocation based on declared lengths. This flaw could lead to potential memory corruption or denial of service, impacting applications that rely on this cryptographic library. Developers and organizations utilizing Bouncy Castle for Java should prioritize upgrading to version 1.85 or later to mitigate these risks.
