NVD Description

Note: Versions mentioned in the description apply only to the upstream libguestfs-rsync package and not the libguestfs-rsync package as distributed by Oracle. See How to fix? for Oracle:8 relevant fixed versions and status.

A flaw was found in the copying tool nbdcopy of libnbd. When performing multi-threaded copies using asynchronous nbd calls, nbdcopy was blindly treating the completion of an asynchronous command as successful, rather than checking the *error parameter. This could result in the silent creation of a corrupted destination image.
