3.2. All Packages

[Note]

Note

Read the security advisories before downloading packages to figure out if a newer version of any package should be used to avoid security vulnerabilities.

The upstream sources may remove old releases, especially when those releases contain a security vulnerability. If one URL below is not reachable, you should read the security advisories first to figure out if a newer version (with the vulnerability fixed) should be used. If not, try to download the removed package from a mirror. Although it's possible to download an old release from a mirror even if this release has been removed because of a vulnerability, it's not a good idea to use a release known to be vulnerable when building your system.

Download or otherwise obtain the following packages:

Note

The Glibc developers maintain a Git branch containing patches considered worthy for Glibc-2.40 but unfortunately developed after Glibc-2.40 release. The LFS editors will issue a security advisory if any security fix is added into the branch, but no actions will be taken for other newly added patches. You may review the patches yourself and incorporate some patches if you consider them important.

[Note]

Note

The Linux kernel is updated quite frequently, many times due to discoveries of security vulnerabilities. The latest available stable kernel version may be used, unless the errata page says otherwise.

For users with limited speed or expensive bandwidth who wish to update the Linux kernel, a baseline version of the package and patches can be downloaded separately. This may save some time or cost for a subsequent patch level upgrade within a minor release.
