Domino TLS POODLE Fix released

Daniel Nashed  21 December 2014 23:30:09
As reported before the IF that introduced TLS 1.0 is vulnerable to the new PODDLE issue.
IBM released a new IF for all supported versions that fixes this issue.
After installing the IF you can re-enable the CBC ciphers which are now reported as not vulnerable by the SSL Labs Test site.

In addition to this fix IBM officially introduces a new notes.ini variable to disable SSL V3.

DISABLE_SSLV3=1 will disable SSL V3 completely. But as mentioned before you should be completely sure if you want to completely disable SSL V3.

SPR #KLYH9QXMQE: Disable SSL ini:
SPR #KLYH9RMJGL: CVE-2014-8730 TLS 1.x Padding Vulnerability

There is a reference technote and a list of IFs for all supported releases.

Thanks Daniel for this update and for the reference to the Domino notes.ini parameter. The "Disable_SSLV3=1" is not in the technote.
