Package: ca-certificates Followup-For: Bug #812488 #813468 is similar but impacting a different application. I did come across a patch which backports the fix included in newer versions of the upstream OpenSSL 1.0.1 branch, to the 1.0.1k derived package in Jessie.
I haven't reviewed or tested the fix tho': https://gist.github.com/h-yamamo/adf44638a1a04b8e86ea Tim.
