Fix the following vulnerabilities:
- [High] Potential for DTLS DoS attack. In wolfSSL versions before
5.4.0 the return-routability check is wrongly skipped in a specific
edge case. The check on the return-routability is there for stopping
attacks that either consume excessive resources on the server, or try
to use the server as an amplifier sending an excessive amount of
messages to a victim IP. If using DTLS 1.0/1.2 on the server side
users should update to avoid the potential DoS attack. CVE-2022-34293
- [Medium] Ciphertext side channel attack on ECC and DH operations.
Users on systems where rogue agents can monitor memory use should
update the version of wolfSSL and change private ECC keys.

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.
