wolfSSL version 4.5.0 contains 6 vulnerability fixes: 2 fixes for TLS 1.3,
2 side channel attack mitigations, 1 fix for a potential private key leak
in a specific use case, 1 fix for DTLS including those 3 CVEs:
- Fix CVE-2020-12457: An issue was discovered in wolfSSL before 4.5.0.
It mishandles the change_cipher_spec (CCS) message processing logic
for TLS 1.3. If an attacker sends ChangeCipherSpec messages in a
crafted way involving more than one in a row, the server becomes stuck
in the ProcessReply() loop, i.e., a denial of service.
- Fix CVE-2020-15309: An issue was discovered in wolfSSL before 4.5.0,
when single precision is not employed. Local attackers can conduct a
cache-timing attack against public key operations. These attackers may
already have obtained sensitive information if the affected system has
been used for private key operations (e.g., signing with a private
key).
- Fix CVE-2020-24585: An issue was discovered in the DTLS handshake
implementation in wolfSSL before 4.5.0. Clear DTLS application_data
messages in epoch 0 do not produce an out-of-order error. Instead,
these messages are returned to the application.

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 Freenode IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
