@pennae:matrix.eno.space@pennae:matrix.eno.spaceoh, there's been an issue closing spree for 21.11 cves :D00:52:55
@hexa:lossy.networkhexahttps://github.com/NixOS/nixpkgs/issues/17476401:31:15
@hexa:lossy.networkhexasure … don't care about security issues for two months and then close it01:31:29
@hexa:lossy.networkhexaI'm not pleased.01:31:43
@qyliss:fairydust.spaceAlyssa RossI wonder what to do about that GnuPG patch06:16:10
@qyliss:fairydust.spaceAlyssa Rossunlike the last one, it hasn't been merged yet06:16:22
@qyliss:fairydust.spaceAlyssa Rossand "werner removed a reviewer: werner."06:16:28
@qyliss:fairydust.spaceAlyssa Ross so it wouldn't surprise me if there's been a falling out and it won't be, at least not any time soon… 06:16:51
@qyliss:fairydust.spaceAlyssa Ross(a falling out due to the disclosure of the previous issue, I maen)06:17:04

@qyliss:fairydust.spaceAlyssa Rosshexa: did I accidentally take on OpenSSL responsibility by renaming the package? :P15:26:41

@stigo:matrix.orgstigoAdded Demi Marie's patch from the last oss-sec post in a PR https://github.com/NixOS/nixpkgs/pull/18033612:17:03
@stigo:matrix.orgstigoIt seems legit to me, but I'm not sure if we should wait from some info from upstream..12:18:46
@stigo:matrix.orgstigoit's a bit annoying that it hasn't gotten a CVE (yet), not sure what to search for to see other discussions about the issue.12:26:28
@linus:schreibt.jetzt@linus:schreibt.jetztHm, signatures wouldn't actually be compressible anyway, right?13:56:06
@stigo:matrix.orgstigoThey can, it seems13:56:44
@hexa:lossy.networkhexahttps://cr.yp.to/sigs/compress.html13:56:53
@stigo:matrix.orgstigoOr, they can be put in a compressed packet13:57:32
@stigo:matrix.orgstigo"By concatenating the same signature to itself a very large number of times, and then wrapping them in a compressed packet, I am able to cause GnuPG to take over a minute to process an input that is less than 5KB armored."13:59:51
@linus:schreibt.jetzt@linus:schreibt.jetztright, but compressed packets are compressed with generic data compression, which is different from what djb describes, and generic data compression wouldn't work well on cryptographic sigs, so disallowing it Should Be Fine™️... right?14:02:41
