This fixes the following vulnerability:
RAUC bundles using the 'plain' format exceeding a payload size of 2 GiB
cause an integer overflow which results in a signature which covers only
the first few bytes of the payload. Given such a bundle with a legitimate
signature, an attacker can modify the part of the payload which is not
covered by the signature. Bundles using the recommended 'verity' or
'crypt' formats are not affected. They are supported from v1.5
(released 2020-12-14) and v1.7 (released 2022-06-03) respectively.
If all signed and published bundles were smaller than 2GiB,
the vulnerability cannot be exploited.

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 https://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.
