openSUSE 15 Security Update : libnbd (SUSE-SU-2022:2347-1)

The remote openSUSE 15 host has packages installed that are affected by a vulnerability as referenced in the SUSE- SU-2022:2347-1 advisory.

  • 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. (CVE-2022-0485)

Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
