Comment 7 Nick Bebout 2017-07-05 17:25:28 UTC

Reopening so I can propose as a F26 Freeze Exception.

Comment 8 Fedora Blocker Bugs Application 2017-07-05 17:27:02 UTC

Proposed as a Freeze Exception for 26-final by Fedora user nb using the blocker tracking app because:

 This is a moderate-impact CVE where libgcrypt/gnupg RSA 1024 has a vulnerability.  I think this would be a nice thing to accept as a freeze exception in the event that we make another RC for Fedora 26.  This update already has +3 karma, and is already pushed to karma in Fedora 25, but 26 is still pending stable.

Comment 9 Ben Williams 2017-07-05 17:34:30 UTC

+1 FE

Comment 10 Adam Williamson 2017-07-05 18:17:05 UTC

+1 FE if we slip, sure.

Comment 11 Mike Ruckman 2017-07-05 18:25:31 UTC

+1 FE if we slip.

Thanks.

Comment 12 Nick Bebout 2017-07-06 13:49:28 UTC
