[Bug 592442] Re: fopen fails on some SSL urls

[Clint Byrum]

Anders, I'm not entirely sure that is the same issue. I've tried an
affected openssl s_client on a few of the other noted servers from other
comments on the bug, and they are not failing. That said, the original
problem with the ucdavis server does not happen anymore for me on Ubuntu
12.04. I think the real problem was PHP not handling the error at all.

Title:
  fopen fails on some SSL urls

Status in PHP: Hypertext Preprocessor:
  Unknown
Status in “openssl” package in Ubuntu:
  Confirmed
Status in “php5” package in Ubuntu:
  Fix Released

Bug description:
  Binary package hint: php5

  Description:	Ubuntu 10.04 LTS
  Release:	10.04

  php5:
    Installed: 5.3.2-1ubuntu4.2
    Candidate: 5.3.2-1ubuntu4.2
    Version table:
   *** 5.3.2-1ubuntu4.2 0
          500 http://archive.ubuntu.com/ubuntu/ lucid-updates/main Packages
          100 /var/lib/dpkg/status

  For some reason I can't seem to get the following to work. I suspect a
  SSL problem. Maybe the intermediate SSL cert is not being recognized
  properly? The server cert is signed by geotrust (which is an
  intermediate of equifax[1]).

  I put the following in a file called /tmp/fopen.php:

  <?php
  if (fopen("https://www.google.com","r")) { print "www.google.com worked\n"; }
  if (fopen("https://cas.ucdavis.edu","r")) { print "cas.ucdavis.edu worked\n"; }
  ?>

  Then I run the php via an apache web and/or via the php5-cli (the
  results are the same in both cases):

  $ php /tmp/fopen.php
  www.google.com worked
  PHP Warning:  fopen(): SSL operation failed with code 1. OpenSSL Error messages:
  error:140773F2:SSL routines:func(119):reason(1010) in /tmp/fopen.php on line 3
  PHP Warning:  fopen(): Failed to enable crypto in /tmp/fopen.php on line 3
  PHP Warning:  fopen(https://cas.ucdavis.edu): failed to open stream: operation failed in /tmp/fopen.php on line 3
  $

  When I run the above command on a karmic or jaunty machine it works
  fine for both fopen() calls. I've attached a tcpdump of the above
  script.

  As you can see from the dump, Google is working but my server is not. I get an SSL alert packet (packet #29) back with code 10
  (unexpected message).  Maybe this is an intermediate cert verification problem?

  What is funny is that I get an ACK right before that. It seems like
  maybe the server is sending an ACK, client starts talking, server
  isn't ready and sends an out-of-order message.
