[Bug 1714506] Re: libgnutls30 OCSP verification bug

[Julian Andres Klode]

** Description changed:

  [Impact]
  
-  * libgnutls30 fails some types of OSCP verification
- 
-  * everybodys doing it
- 
-  * https://gitlab.com/gnutls/gnutls/merge_requests/433/commits
+ Applications using GnuTLS fails to verify OSCP, especially when ECDSA is
+ involved, which becomes increasingly more popular.
  
  [Test Case]
+ Run gnutls-cli -p 443 tvemsnbc-vh.akamaihd.net it should succeed, but fails the handshake with certificate validation.
  
-  * https://gitlab.com/gnutls/gnutls/issues/223
+ [Regression Potential]
+ Only OCSP code is affected by the fixes, so something could possibly break there.

+ This was fixed in Debian stretch in 3.5.8-5+deb9u3:
