CVE-2022-0485
This could result in the silent creation of a corrupted destination image.
MEDIUM 4.8EPSS 0.97%
Does this matter?
Lower severity and a low EPSS score (0.97%). Track it; it rarely justifies an emergency change on its own.
Description
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.
