@gggkiller:matrix.orgGGG I wonder what's the likelyhood of c3ab8ff13720e8ad9047dd39466b3c8974e592c2fa383d4a3960714caef0c4f2 appearing in a normal binary 13:49:39
@gggkiller:matrix.orgGGGmaybe as a set of bytes it could happen, but as a sequence of ASCII characters I'm not sure13:49:51
@corngood:corngood.comCorngoodI think that would depend on where it came from. Maybe I can track that down.13:50:32
@corngood:corngood.comCorngoodIf it's guid-ish then ~013:50:46
@gggkiller:matrix.orgGGG I'm doing a simple preliminary test by doing grep -sRl 'c3ab8ff13720e8ad9047dd39466b3c89' /nix/store 13:50:55
@gggkiller:matrix.orgGGGit seems like they just SHA-256'd "foobar"13:51:13
@gggkiller:matrix.orgGGGaccording to the comment on the code you posted13:51:19
@corngood:corngood.comCorngoodoh, lol. that was stupid of them13:51:29
@corngood:corngood.comCorngoodit's probably fine, but they could have easily avoided the possibility of someone else doing the same thing13:51:59
@corngood:corngood.comCorngoodstill, they were only concerned about their codebase and dependencies13:52:28
@corngood:corngood.comCorngoodwe don't need to differentiate already-patched or source-built binaries, do we?13:53:39
@gggkiller:matrix.orgGGGno, this was only so I could make a hook to do the patching we do for pre-built .NET apps13:54:13
@gggkiller:matrix.orgGGGthat adds the whole ICU, Kerberos, OpenSSL and etc. deps13:54:25
@corngood:corngood.comCorngoodBut I mean we're not mixing other stuff in the same outputs that are being patched?13:56:10
@gggkiller:matrix.orgGGGeven if we do, there shouldn't be any harm I think13:56:36
