Jason, it'd probably be best to file a new bug report, openssl and
apache have both changed a fair amount in the last five years.

Thanks

Title:
  Intermittent SSL connection faults when using TLSv1

Status in OEM Priority Project:

Status in apache package in Ubuntu:

Bug description:
  Binary package hint: openssl

  Reported intermittent SSL connection issue on some apache mod_ssl
  vhosts.

  Platform:  Ubuntu 10.04.2 LTS
  Tested: Apache2-2.2.14-5ubuntu8.4 and backported 2.2.17-1ubuntu1 from Natty

  Firefox client will intermittently report:
  Secure Connection Failed
  An error occurred during a connection to oem-ibs.canonical.com.
  Peer's certificate has an invalid signature.
  (Error code: sec_error_bad_signature)

  Condition will clear on reload.

  Occassionally the server will alternately serve a good page followed
  by an SSL error until Apache is restarted. I am unable to reproduce
  the condition on demand, but have output from when the fault occurs.
  When the fault condition occurs it can be reproduced with any SSL
  client.

  The fault presents on multiple distinct servers.

  Initially suspected to be a bug with mod_ssl
  https://issues.apache.org/bugzilla/show_bug.cgi?id=46952, backport has
  eliminated this as has anecdotal reports of this same error presented
  from Dovecot.

  Tested with SSL certs from different CAs.

  Example:

  $ openssl s_client -connect oem-ibs.canonical.com:443
  CONNECTED(00000003)
  depth=2 /C=US/O=thawte, Inc./OU=Certification Services Division/OU=(c) 2006 thawte, Inc. - For authorized use only/CN=thawte Primary Root CA
  verify error:num=20:unable to get local issuer certificate
  verify return:0
