Log Message:
security/wolfssl: Updates to v4.8.0

Changes since v4.7.0:

wolfSSL Release 4.8.0 (July 09, 2021)

Release 4.8.0 of wolfSSL embedded TLS has bug fixes and new features including:
Vulnerabilities

  * [Low] OCSP request/response verification issue. In the case that the serial
    number in the OCSP request differs from the serial number in the OCSP
    response the error from the comparison was not resulting in a failed
    verification. We recommend users that have wolfSSL version 4.6.0 and 4.7.0
    with OCSP enabled update their version of wolfSSL. Version 4.5.0 and earlier
    are not affected by this report. Thanks to Rainer, Roee, Barak, Hila and
    Shoshi (from Cymotive and CARIAD) for the report.
  * [Low] CVE-2021-24116: Side-Channel cache look up vulnerability in base64 PEM
    decoding for versions of wolfSSL 4.5.0 and earlier. Versions 4.6.0 and up
    contain a fix and do not need to be updated for this report. If decoding a
    PEM format private key using version 4.5.0 and older of wolfSSL then we
    recommend updating the version of wolfSSL used. Thanks to Florian Sieck, Jan
    Wichelmann, Sebastian Berndt and Thomas Eisenbarth for the report.
