[Bug 1356843] Re: ccs received early errors after openssl security update

 

There also is an issue with the openssl package in Lucid, which was worked around with the postfix fix.
Adding openssl to this bug since it's better if we fix both.

Bug description:
  SRU request:

  [Impact]

  The CVE-2014-0224 update for openssl will now reject CCS messages when
  they are received before encryption is negotiated. This has caused an
  issue for certain sites attempting to send mail to Ubuntu 12.04
  servers running postfix. It turns out there is an incompatibility
  between postfix in Ubuntu 12.04 and openssl in 12.04 that mishandles
  session ids. This was fixed in Postfix 2.10.2, and the minimal fix is
  included in this debdiff.

  [Test Case]
  Server A = Ubuntu 10.04 with postfix configured to forward mail, ie:

  relayhost = server b's FQDN
  smtp_tls_security_level = encrypt

  Server B = Ubuntu 12.04 with postfix configured to receive mail with
  forced tls:

  smtpd_tls_security_level = encrypt

  Send more than one mail from Server A to Server B, and see if the following error appears in mail.log:
  warning: TLS library problem: 31807:error:14094085:SSL routines:SSL3_READ_BYTES:ccs received early:s3_pkt.c:1146:

  [Regression potential]
  This patch disables TLS session tickets, which is what later postfix versions do. If this introduces a regression, it may cause TLS to ether fail completely, or to break when resuming sessions.

  Postfix is causing a TLS error, when relaying mails with TLS encryption:
