- Fix CVE-2022-47952: lxc-user-nic in lxc through 5.0.1 is installed
setuid root, and may allow local users to infer whether any file
exists, even within a protected directory tree, because "Failed to
open" often indicates that a file does not exist, whereas "does not
refer to a network namespace path" often indicates that a file exists.
NOTE: this is different from CVE-2018-6556 because the CVE-2018-6556
fix design was based on the premise that "we will report back to the
user that the open() failed but the user has no way of knowing why it
failed"; however, in many realistic cases, there are no plausible
reasons for failing except that the file does not exist.
