[00:19] <amurray> ItzSwirlz: it could be treated as a security issue (denial of service) depending on what the application is and how it can be triggered - can you elaborate more? |
|
[00:20] <ItzSwirlz> https://github.com/linuxmint/cinnamon-desktop/commit/1b44b9ccc92d8479da3bcd37921c80e64f7d2e91 |
|
[00:20] <ItzSwirlz> so in this case, if you ahve a connected but disabled monitor there can be problems and it might end up dividing by 0 |
|
[00:20] <ItzSwirlz> 1/(0/1) |
|
[00:21] <ItzSwirlz> hold on, I'm going to look at the function |
|
[00:23] <ItzSwirlz> It's with the scaling of the monitor-so say you have two monitors and one is off. Basically-cinnamon-desktop is libraries |
|
[00:23] <ItzSwirlz> So it's saying that if something wanted to call it to get the monitor information, it could scale it and cause math that divy's by 0 |
|
[00:48] <ItzSwirlz> However the patch just got placed today so I think wait it out |
|
[00:49] <tumbleweed> sonuds like a bug worth SRUing |
|
[00:56] <ItzSwirlz> I'll take your word for it-but let's wait it out until December when upstream's distro gets released and any extra patches come with it |
|
[00:56] <ItzSwirlz> y'know in case *cough* regression |
|
[00:57] <ItzSwirlz> Anyone willing to take a look at reviewing my patch for in the Cinnamon Desktop Libraries, using -- flag when launching the terminal instead of using -x? (Bug #1905630) |
|

|
[00:58] <sarnold> ItzSwirlz: is that patch the wrong way around? it's removing a changelog entry |
|
[00:58] <sarnold> most of it is removing things |
|
[00:59] <ItzSwirlz> the frick? lemem see |
|
[00:59] <ItzSwirlz> Oh. oh. oh. |
|
[00:59] <ItzSwirlz> Yes! Totally a great idea to REVERSE THE DSC ORRDER. |
|
[00:59] <ItzSwirlz> a.k.a i took the old thing over the new one lol |
|
[01:00] <sarnold> ItzSwirlz: what happens if the script or directory is named something really stupid like $(touch /tmp/HELLO) or `touch /tmp/HELLO` or other ridiculously bad names? |
|
[01:01] <ItzSwirlz> As long as it's an executable |
|
[01:01] <sarnold> it just seem slike anything that breaks on something as common as a space is liable to blow up into a billion pieces when faced with something actually malicious |
|
[01:05] <ItzSwirlz> sarnold: okay so- |
|
[01:05] <ItzSwirlz> gnome-terminal -x (thing) |
|
[01:05] <ItzSwirlz> gnome-terminal -- (thing) |
|
[01:06] <ItzSwirlz> Thats all the patch does. As a matter of fact if you try running gnome-terminal -x (blah) in a terminal, it will even tell you its deprecated and perfers a -- |
|
[01:06] <ItzSwirlz> Oh... |
|
[01:06] <ItzSwirlz> gnome-terminal -x is not even an option. It got removed per-groovy. |
|
[01:06] <ItzSwirlz> ¯\_(ツ)_/¯ |
|
[01:07] <sarnold> ItzSwirlz: but why does it break with a space in the directory name? |
|
[01:26] <ItzSwirlz> doesn't bash technically break with a space in the dir name? |
|
[01:26] <ItzSwirlz> you have to do some quite funky stuff with it, with the \ and the / |
|
[01:28] <cjwatson> Or just normal quoting |
|
[01:28] <cjwatson> bash is fine, it's just that lots of scripts aren't carefully written |
|
[01:28] <cjwatson> I mean "fine" in implementation terms, not going to defend it as a language |
|
[01:29] <sarnold> :) |
|
[01:30] <cjwatson> And I agree with sarnold's guess here. It *might* be fine, but this is a red flag for more serious security bugs |
|
[01:30] <cjwatson> Needs a full root cause analysis IMO |
|
[01:32] <ItzSwirlz> If thats the cause then it's because C code |
|
[01:32] <cjwatson> Without having looked at the actual software, there are two likely possibilities here |
|
[01:32] <ItzSwirlz> Which technically would mean go through all the programs and patching it |
|
[01:32] <cjwatson> (1) unlikely but possible: something is manually splitting on spaces and constructing an argument list that way |
|
[01:33] <cjwatson> (2) more likely: something is violating the rule of one layer of quoting per layer of expansion |
|
[01:33] <ItzSwirlz> does this apply upstream? |
|
[01:33] <cjwatson> I have no idea, I haven't done a root cause analysis |
|
[01:34] <cjwatson> If it's (2) it can probably be turned into a security vulnerability |
|
[01:34] <cjwatson> If it's (1) it's probably just poor-quality |
|
[01:34] <ItzSwirlz> well remember its a library |
|
[01:34] <cjwatson> Do you understand shell quoting rules? |
|
[01:34] <ItzSwirlz> The fix for the GitHub upstream bug was technically in the Nemo source code |
|
[01:34] <ItzSwirlz> Pretty sure, yes |
|
[01:35] <cjwatson> Do you understand how argument lists work at the C level? |
|
[01:35] <ItzSwirlz> No |
|
[01:37] <ItzSwirlz> hold on-you talking about the good ol bash -c 'command' |
|
[01:37] <cjwatson> Not really |
|
[01:38] <sarnold> more execve(2) syscall vs system(3) library call level |
|
[01:38] <ItzSwirlz> hm. i'll take a quick glance at it |
|
[01:38] <cjwatson> OK, so when you fork and exec a process at the C level, there should normally not be any shell parsing involved. Instead what you do is construct a list of arguments which the subsidiary program receives in its argv vector. Those are *not quoted* (except for the quoting required by the C language): so the equivalent of running something like some-program 'foo bar' '"foo bar baz"' in ... |
|
[01:38] <cjwatson> ... shell is an argv of ["some-program", "foo bar", "\"foo bar baz\""] in C |
|
[01:39] <cjwatson> Sometimes programs use the system() C library call, which effectively runs a string through sh -c. This is extremely often a source of bugs |
|
[01:39] <cjwatson> Because in order to get that right, you have to accurately reverse the shell's parsing, i.e. accurately quote everything |
|
[01:40] <cjwatson> When executing programs from C, it is very much safer to avoid shell parsing entirely |
|
[01:40] <ItzSwirlz> So in this case (this commit which is one of the things done after the schema update I'm considering SRU) at https://github.com/linuxmint/nemo/commit/a2f15e045b5b2d0581bcc10780b3416ea185faa3 |
|
[01:40] <ItzSwirlz> g_strdup_printf ("gnome-terminal -x"); - so i'll go see what's really going on |
|
[01:41] <sarnold> twisty maze of abstractions.. |
|
[01:41] <ItzSwirlz> Yep. Typical GTK shenanigans |
|
[01:41] <ItzSwirlz> but again yes it could just be bad programming quality |
|
[01:41] <cjwatson> GTK has perfectly good list-based interfaces for subprocesses |
|
[01:41] <cjwatson> Or Glib rather |
|
[01:42] <cjwatson> And yeah, that prepend_terminal_to_command_line function gives me the shivers |
|
[01:43] <cjwatson> Difficult because its interface involves taking a shell command and modifying it, so it's hard to get right by design |
|
[01:45] <cjwatson> A proper fix would probably involve rewriting its interface (and thus its callers) to use argument lists, but it could be patched up with g_shell_quote |
|
[01:45] <sarnold> this looks like it'll take that string and do a bunch of % substitutions via https://specifications.freedesktop.org/desktop-entry-spec/latest/ar01s07.html ... this feels like it's ripe for abuse. I didn't consider scripts named %f or %F or similar. |
|
[01:45] <cjwatson> Not sure whether that's actually what you're running into here |
|
[01:47] <cjwatson> Anyway I need to sleep, it's just that I feel like I've spent most of my career trying to persuade people to get subprocess invocations right :) |
|
[01:48] <ItzSwirlz> Yeah. I hope I didn't tangle you or piss you off. |
|
[01:48] <ItzSwirlz> I'm easy to do that with my dumb and empty brain capabilities |
|
[01:48] <ItzSwirlz> gn o7 |
|
[01:48] <ItzSwirlz> I'll mark the issue as "invalid" |
|
[01:48] <cjwatson> Oh you didn't piss me off, and probably the issue isn't invalid |
|
[01:48] <cjwatson> Just needs deeper fixing |
|
[01:48] <ItzSwirlz> ok |
|
[01:48] <ItzSwirlz> Well good thing it's version 4.8 and next version is 5.0, a major! :D |
|
[01:48] <ItzSwirlz> ok go to sleep, take care |
|
[01:49] <cjwatson> Parting note, a friend of mine wrote http://www.greenend.org.uk/rjk/tech/shellmistakes.html#missingquote which is an excellent primer on how shell quoting works without having to load the entire bash man page into your head all at once |
|
[01:50] <ItzSwirlz> o. ty |

|
[13:55] <seb128> sil2100, yes, I was about to ping you |
|
[13:55] <seb128> /usr/share/livecd-rootfs/get-ppa-fingerprint failing to connect error |
|
[13:56] <seb128> I'm not familiar with get-ppa-fingerprint though, let me try to understand what that does and if it's something weird canary is doing... |
|
[13:59] <seb128> sil2100, I see you asked about that error on the launchpad channel in octobre :) |
|
[13:59] <seb128> how did you fix it at the end? |
|
[14:00] <cjwatson> It's a get-ppa-fingerprint bug |
|
[14:01] <cjwatson> Missing a 'production' second argument |
|
[14:01] <cjwatson> I thought xnox was fixing it |
|
[14:01] <cjwatson> (If you don't specify a service, it defaults to staging) |
|
[14:01] <seb128> cjwatson, thanks |
|
[14:01] <seb128> I wonder why it's impacting the canary build only, that code doesn't seem specific to this image... |
|
[14:01] <cjwatson> Is it possibly only affecting riscv64? |
|
[14:02] <cjwatson> If so it's some quirk of firewall rules - the other builders can only get at staging basically by accident |
|
[14:02] <seb128> cjwatson, that's an amd64 build, https://launchpadlibrarian.net/508742975/buildlog_ubuntu_hirsute_amd64_ubuntu-canary_BUILDING.txt.gz |
|
[14:02] <cjwatson> Or maybe other images don't use extra_ppas |
|
[14:02] <cjwatson> Which would mean that code isn't used |
|
[14:02] <cjwatson> This code was only broken in around August |
|
[14:03] <seb128> canary had been commented for a while since it had other issues which I finally fixed |
|
[14:03] <seb128> cjwatson, thanks for the reply, I will check with xnox what's the status of the get-ppa-fingerprint bug |
|
[14:04] <seb128> cjwatson, but yes, seems like the canary image uses --extra-ppa ubuntu-desktop/canary-image |
|
[14:04] <cjwatson> Looks like it's fixed in livecd-rootfs 2.702 |
|
[14:04] <seb128> which would explain the difference with standard desktiop |
|
[14:05] <seb128> ah |
|
[14:05] <cjwatson> livecd-rootfs | 2.700 | hirsute | source, amd64, arm64, armhf, i386, ppc64el, riscv64, s390x |
|
[14:05] <cjwatson> livecd-rootfs | 2.702 | hirsute-proposed | source, amd64, arm64, armhf, i386, ppc64el, riscv64, s390x |
|
[14:05] <seb128> right, that iso build has 2.700 |
|
[14:06] <seb128> so to migrate it needs ubuntu-image autopkgtests to be fixed it seems |
|
[14:13] <sil2100> seb128: do we need the extra PPAs in the meantime? |
|
[14:13] <seb128> sil2100, I don't know, but I'm fixing ubuntu-image :) |
|
[14:13] <seb128> we need livecd-rootfs to migrate anyway, I've other fixes in 702 needed for canary |
|
[14:14] <sil2100> +1 |
|
[14:14] <sil2100> I didn't see the u-i failures, but I see I got poked about those on -release |
|
[14:15] <seb128> I've a fix ready to test |
|
[14:17] <sil2100> seb128: ah, it's due to the python defaults switching to 3.9, yeah |
|
[14:17] <sil2100> seb128: give me a poke once you test, I can commit that in the upstream repo then |
|
[14:17] <seb128> sil2100, the issue I'm fixing in not that one |
|
[14:17] <seb128> I'm fixing the |
|
[14:17] <seb128> AttributeError: 'Changelog' object has no attribute 'get_version' |
|
[14:19] <seb128> which is a change in the newest python-debian |
|
[14:24] <sil2100> Ah, I see, they did get_version() -> _get_version(), which is weird, as that's basically changing the API without notice |
|
[14:28] <seb128> sil2100, right, I don't know if that's an error or not, there was a similar failure there https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=973227#10 where the maintainer said the method was undocumented |

[14:42] <sil2100> seb128: feel free to upload, I guess it'll be faster as you already have everything prepped |
|
[14:43] <seb128> sil2100, thanks |
|
[14:45] <seb128> sil2100, bah, sorry, I just saw that the launchpad git is an import from github, I can redo the mp there |
|
[14:49] <sil2100> seb128: no worried, I'll sync it |
|
[14:49] <seb128> sil2100, k, thanks |
|
[15:02] <seb128> sil2100, I pushed to github anyway, https://github.com/CanonicalLtd/ubuntu-image/pull/195 so we have CI and you just have to press the button |
|
[15:02] <seb128> sil2100, you might still want to tag 1.10+20.10ubuntu3 and push, unsure the mp handles that part correctly |
|
[15:15] <sil2100> seb128: hah, I just prepared a PR for that as well! Since I wanted to skip 1.10+20.10ubuntu3 in the upstream changelog out of stylistic reasons - but anyway, no harm done, good that it's there |
|
[15:16] <sil2100> For devel series specific fixups we don't always tag a release, especially that 1.10+20.10ubuntu3 is a groovy version number released to hirsute, so it's a bit of a bandaid release anyway |
|
[15:17] <sil2100> Though I don't really have preferences, sometimes I just push those fixes up and stage them for the next big upstream release (so for 1.11) |
|
[15:17] <sil2100> This is why I said I'll do it as I wanted to do it 'my way' ;) |
|
[15:20] <sil2100> (also, had to enable hirsute CI since it was disabled) |
|
[15:20] <sil2100> Your PR was a bit early before I did that so it wasn't set up yet ;) |
|
[15:25] <seb128> sil2100, k, no worry, I just didn't want to create more work for you, at least I feel like I've not been lazy letting things for you to clean, feel free to reject the MPs or do things the way you prefer, I'm not picky on details :) |
|
[15:26] <sil2100> seb128: thanks for prepping the quick-fix! |
|
[15:28] <seb128> np! |
|
[15:32] <xnox> seb128: you could force copy livecd-rootfs to release pocket ;-) you have the powers =) |
|
[15:32] <seb128> xnox, :) |
|
[15:32] <xnox> seb128: or you can copy livecd-rootfs into the canary ppa. that should work too. |
|
[15:33] <seb128> xnox, would that work since it errors out trying to enable that ppa? :p |
|
[15:33] <seb128> xnox, i need the get-ppa-fingerprint fix |
|
[15:33] <xnox> seb128: yes, because the livecd-rootfs is installed from that ppa too. |
|
[15:33] <seb128> ah |
|
[15:33] <xnox> on the host, before trying to enable said ppa. |
|
[15:33] <seb128> xnox, anyway I'm not in an hurry, hopefully the ubuntu-image fix uploaded is enough and things migrate today |
|
[15:54] <xnox> what do I use to grant queue rights to myself for a PPA? |
|
[15:55] <xnox> acutally with queue tool i don't see that anything needs doing. |
|
[15:55] <cjwatson> edit-acl |
|
[15:55] <xnox> ah, thanks. |
|
[15:55] <xnox> i was greping for "grant" for some reason. |
|
[17:17] <LocutusOfBorg> hello Unit193, what happened to the libtorrent-rasterbar package? |
|
[17:17] <LocutusOfBorg> do you want to merge it? there is also a tarball mismatch, and the remaing delta should probably be upstreamed |

[18:14] <ItzSwirlz> arm builds being out is a pain. |
|
[18:19] <mitya57> kanashiro: it looks like rubygems is built, so I think you can try. In the worst case we will have to remove it from -proposed again. |
|
[18:20] <kanashiro> mitya57: it is working on Debian now, so I do not expect any major issue |
|
[18:20] <mitya57> kanashiro: though I'm not sure if a simple sync will work. Maybe you will have to ask some archive admin to get it re-published instead. |
|
[18:21] <kanashiro> mitya57: you are right, I got it rejected when trying to use syncpackage |
|
[18:22] <mitya57> Maybe vorlon or doko will be able to fix it |
|
[18:23] <mitya57> (re-publish https://launchpad.net/ubuntu/+source/ruby-defaults/1:2.7+2) |
|
[18:24] <kanashiro> I also asked archive admins in #ubuntu-release |
|
[18:32] <cjwatson> ItzSwirlz: They aren't out any more though? |
|
[18:33] <LocutusOfBorg> mitya57, I did that |
|
[18:33] <LocutusOfBorg> ./copy-package --from=ubuntu --to=ubuntu --from-suite=hirsute-proposed --to-suite=hirsute-proposed --include-binaries ruby-defaults --version 1:2.7+2 --force-same-destination |
|
[18:33] <cjwatson> That's why I removed it from the topic |
|
[18:33] <LocutusOfBorg> we cannot remove them, but we can restore them |
|
[18:33] <ItzSwirlz> cjwatson: just woke up. Polari didn't update :P soz. Happy days, happy thanksgiving if celebrating |
|
[18:38] <mitya57> LocutusOfBorg: cool, I didn't know about that :) |
|
[18:39] <LocutusOfBorg> mitya57, ssssh don't tell anybody! |
|
[22:23] <Unit193> LocutusOfBorg: Yeeeah, I noticed that... |
|
[22:38] <Unit193> LocutusOfBorg: Also no reason to keep delta, IMO. |
