How to fix?

Upgrade Debian:unstable libnbd to version 1.22.5-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libnbd package and not the libnbd package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

A flaw was found in libnbd. A malicious actor could exploit this by convincing libnbd to open a specially crafted Uniform Resource Identifier (URI). This vulnerability arises because non-standard hostnames starting with '-o' are incorrectly interpreted as arguments to the Secure Shell (SSH) process, rather than as hostnames. This could lead to arbitrary code execution with the privileges of the user running libnbd.
