After patching a windows 7 computer with MS12-006, can no longer connect to elog, get page cannot be displayed

 A little more information here

We are running elog on an Ubuntu server

Elog was working fine, then, on a windows 7 machine, MS12-006 was installed, rebooted, and could no longer connect to the elog web page.

Discovered that in Internet Explorer 8, by unchecking the use TLS 1.0 in options advanced tab, and making sure that SSL 3.0, TLS 1.1, TLS 1.2 were checked, that the page once again worked.  I'm guessing the elog does not support SSL 3.0, otherwise, I assume I would have to uncheck that as well.  Things do appear to still work on XP, thus far, only Windows 7 appears to break.  While we have a work around, ideally we would like to see a bug fix so that (for legacy reasons), elog will still work with TLS 1.0 on Windows 7.

 

 Also, strangely, I am able to use the elog forum page https://midas.psi.ch/elogs/Forum while TLS 1.0 is checked.  I notice the version number is 2.9.0-2425, while we are using 2.9.0-2396, so wondering if this is fixed in this newer version.

The forum does not use TLS, but has Apache in front of it which works as a proxy. So TLS is actually handled by Apache, which might have a newer implementation of TLS. The ELOG version number certainly does not make a difference, I did not touch the SSL functionality in a while. But when you compile ELOG on your Ubunto server, you can maybe play with different versions of OpenSSL and see if that changes anything?
