Overview

Affected versions of this package are vulnerable to Authentication Bypass due to data corruption via the dnode_is_dirty() function in dnode.c. In certain scenarios involving applications that attempt to rely on efficient copying of file data, the system can replace file contents with zero-valued bytes, disabling security mechanisms.
