[opensuse-security] openSUSE 13.1 and weakdh.org
Hi, we have several webservers using apache and openSUSE 13.1. https://www.ssllabs.com/ssltest/ rates these systems with an overall rating "B", because "/This server supports weak Diffie-Hellman (DH) key exchange parameters./". The recommendations on https://weakdh.org/sysadmin.html can not be used because the apache directive SSLOpenSSLConfCmd needs apache 2.4.8 and openSUSE 13.1 is using 2.4.6. The other suggestion to append the DHparams to the end of the certificate file does also not work, because you need apache 2.4.7 for that. I found ticket https://bugzilla.suse.com/show_bug.cgi?id=931723 from May 2015 in Status "NEW". There is a comment from "/Swamp Workflow Management ////2015-10-06 07:09:35 UTC/", that there should be a fix for openSUSE 13.1 with apache2-2.4.6-6.50.1, but a "rpm -q --changelog apache2" does not mention this problem and the various patches of the src-rpm do not match, too. / /Any suggestions?

Hi, I have read it. The patch is just hard to backport sadly. Ciao, Marcus On Tue, Nov 24, 2015 at 02:43:36PM +0100, Tobias Hennerich wrote:

Hi Marcus, thank you for your mail. So the comment #21 from "swamp workflow management" in ticket 931723 is just wrong (at least concerning 13.1) ?

Hi Thats strange indeed. According to the BZ track, this problem should have been addressed. Investigating why this is apparently not the case with the built rpms... regards Sebastian On Tue, Nov 24, 2015 at 02:43:36PM +0100, Tobias Hennerich wrote:

Hi all, three weeks later, still no news to this topic. Is there any hope left, that this problem will be fixed sometime in the future?

HI, I revived my test patch, if you would like to test it. This is a ssl backport from 2.4.10 to 2.4.6. Alternatively we could also remove the 512 and 1024 bit group and add a fixed 2048 bit group, which would be more minimal.
