Affected versions of this package are vulnerable to Memory Allocation with Excessive Size Value in the readOpaque() method of MLSInputStream, which decodes a varint length up to 0x3FFFFFFF (about 1 GiB) and calls readAll(size) performing new byte[size] before checking that enough bytes remain in the stream. An attacker can exhaust the JVM heap and crash the process by sending a ~6-byte MLS message whose first opaque length varint is 0xBFFFFFFF, forcing a ~1 GiB allocation per message. This requires only the ability to send raw MLS bytes to the application, since the allocation occurs before any signature or MAC verification.
