@hexa:lossy.networkhexa * full thread for those w/o twatter18:08:44
@vcunat:matrix.orgvcunatNot sure. I read the thread that workarounds will be known on Oct 6, so I'm not sure how specific it will be on Sep 30.18:12:51
@emilazy:matrix.orgemilyopenwall presumably means the private distros list that we're not on18:13:19
@emilazy:matrix.orgemily this is a time it would be really nice to have a representative there even if we can't do secret Hydra builds 18:13:41

@arianvp:matrix.orgArianThis affects all nix versions. We need to make PRs for all the backports too no?12:34:17
@arianvp:matrix.orgArianNot just 2.24-specific afaics12:34:25
@emilazy:matrix.orgemily yes. looks like 2.18 is out, someone should open a PR. no other versions yet, waiting for Eelco to cut the tags I assume. (further discussion should probably go in #security-discuss:nixos.org) 12:35:40

builtin:fetchurl: Enable TLS verification

I would argue the "information leak" should not affect many people. <nix/fetchurl.nix> is manly used by bootstrap tarballs.

* I would argue the "information leak" should not affect many people. <nix/fetchurl.nix> is manly used by bootstrap tarballs that do not suffer from this. So low impact for most people.

@hexa:lossy.networkhexa it probably doesn't, but that is for #security-discuss:nixos.org 18:52:36
