Fix CVE-2021-33560: Libgcrypt before 1.8.8 and 1.9.x before 1.9.3
mishandles ElGamal encryption because it lacks exponent blinding to
address a side-channel attack against mpi_powm, and the window size is
not chosen appropriately. (There is also an interoperability problem
because the selection of the k integer value does not properly consider
the differences between basic ElGamal encryption and generalized ElGamal
encryption.) This, for example, affects use of ElGamal in OpenPGP.

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.
