| Doc Text: |
A flaw was found in Bouncy Castle for Java. A remote attacker could exploit this by providing a specially crafted message to the MLS wire decoder. The decoder allocates an attacker-declared opaque length without first performing a bounds check. This can lead to excessive memory allocation, resulting in a Denial of Service (DoS) for the application.
