[Bug 1636124] Re: openssl lacks support for TLSv1 and TLSv1.1

[ChristianEhrhardt]

Hi,
thank you for your report and helping to make Ubuntu better.

it might be totally true that some issue affects the connectivity of
some browsers - like the one of the cellphone you mentioned. But I'd
question the test you used in regard to TLSv1 support.

But IIRC that list just means that by default it is using TLSv1.2.

This isn't some sort of regression (here Trusty):
lxc exec trusty-tests -- openssl ciphers -v | awk '{print $2}' | sort | uniq
SSLv3
TLSv1.2


Also I can on Xenial just nicely connect via TLSv1, TLSv1.1 and TLSv1.2

openssl s_client -connect www.example.com:443 -tls1
CONNECTED(00000003)
[...]
    Protocol  : TLSv1
[...]
    Verify return code: 0 (ok)

openssl s_client -connect www.example.com:443 -tls1_1
CONNECTED(00000003)
[...]
    Protocol  : TLSv1.1
[...]
    Verify return code: 0 (ok)

openssl s_client -connect www.example.com:443 -tls1_2
CONNECTED(00000003)
[...]
    Protocol  : TLSv1.2
[...]
    Verify return code: 0 (ok)

I'd expect that some part of your stack disabled TLSv1 and/or TLSv1.1
for security reasons as they are deprecated for quite some time now.

Title:
  openssl lacks support for TLSv1 and TLSv1.1

Status in openssl package in Ubuntu:
  Incomplete

Bug description:
  OpenSSL in xenial (16.04) apparently lacks ciphers for both TLSv1 and
  TLSv1.1. This is causing problems, as my wife's mobile phone with an
  older version of Android does not support TLSv1.2 and thus cannot
  connect to my server running on 16.04 (Apache with mod_ssl).

  Can you please rebuild OpenSSL with the secure ciphers from TLSv1 and
  TLSv1.1 enabled?

  For reference, this list should also include TLSv1 and TLSv1.1: 
  openssl ciphers -v | awk '{print $2}' | sort | uniq
  SSLv3
  TLSv1.2
