- 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.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC.
