CVE-2022-0485

Date: August 29, 2022

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.
