Alpine: lxc: security update to 4.0.10-r2

low Tenable Self-Hosted Container Security Plugin ID 405486

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2022-47952)
