# ix. Errata and Security Advisories

The software used to create an LFS system is constantly being updated and enhanced. Security warnings and bug fixes may become available after the LFS book has been released. To check whether the package versions or instructions in this release of LFS need any modifications—to repair security vulnerabilities or to fix other bugs—please visit https://www.linuxfromscratch.org/lfs/errata/12.0-rc1/ before proceeding with your build. You should note any changes shown and apply them to the relevant sections of the book as you build the LFS system.

In addition, the Linux From Scratch editors maintain a list of security vulnerabilities discovered after a book has been released. To read the list, please visit https://www.linuxfromscratch.org/lfs/advisories/ before proceeding with your build. You should apply the changes suggested by the advisories to the relevant sections of the book as you build the LFS system. And, if you will use the LFS system as a real desktop or server system, you should continue to consult the advisories and fix any security vulnerabilities, even when the LFS system has been completely constructed.
