Bug#772055: libgnutls-deb0-28:amd64: Certificate Status Request (OCSP stapling) check fails with mozilla.org

Package: libgnutls-deb0-28
Version: 3.3.8-5
Severity: normal


I've been playing with GnuTLS OCSP stapling support, but I noticed that it seems
to reject apparently valid responses (e.g. the mozilla.org one).

I attached a "simple" code example that connects to a server and checks the
stapled OCSP response using gnutls_ocsp_status_request_is_checked().

Compile with "cc ocsp.c -lgnutls" and run with "./a.out <host> <port>".

For example if I run it against mozilla.org, I get:

  % ./a.out mozilla.org 443
  Certificate check FAIL

but other hosts work fine:

  % ./a.out tn123.org 443
  Certificate check OK

and OpenSSL works fine with both.
