According to Errata this is no more under Embargo.
Before pushing the patches publicly, it this true? Was the errata released?
Comment 8 Doran Moppert 2017-01-31 00:28:20 EST 
Hi Christophe,

errata are nearly ready for push, so I'm targetting an unembargo date of 2017-02-06 (Monday).  If this date works for you, please let me know and I'll arrange notification to other distributions via linux-distros@openwall.org and include copies of the patches against trunk from bug 1401038, bug 1399161.

Apologies for the delays and confusion with this - people being away with shutdown, PTO and devconf, and my own mis-handling of the errata, made this take longer than it should have.

Thanks for your patience and communication throughout!
Comment 9 Christophe Fergeau 2017-01-31 04:54:02 EST 
Yup, sounds good to me, thanks for the update!
