An authenticated user can provide a malformed ACL to the fileserver's StoreACL RPC, causing the fileserver to crash, possibly expose uninitialized memory, and possibly store garbage data in the audit log. Malformed ACLs provided in responses to client FetchACL RPCs can cause client processes to crash and possibly expose uninitialized memory into other ACLs stored on the server.
