hexa	In reply to @aloisw:kde.org I'm not aware of any specific security fixes or `knownVulnerabilities` in Thunderbird, it's just a browser engine so it's probably better to assume every release is security-relevant. basically they track the esr cycle of firefox (up until now), which regularly comes with a security advisory attached	18:05:47
hexa	In reply to @aloisw:kde.org Lol this literally is every release, right? yes.	18:06:05
hexa	In reply to @emilazy:matrix.org yes, though like their notice says probably a lot of them are effectively irrelevant for a product that doesn't (or at least tries not to?) run untrusted JS you can open a website in thunderbird fwiw	18:06:22
emily	Security Vulnerabilities fixed in Thunderbird 115.10 CVE-2024-3864: Memory safety bug fixed in Firefox 125, Firefox ESR 115.10, and Thunderbird 115.10 Memory safety bug present in Firefox 124, Firefox ESR 115.9, and Thunderbird 115.9. This bug showed evidence of memory corruption and we presume that with enough effort this could have been exploited to run arbitrary code. (April) Update request: betterbird 115.9 → 115.12 #323169 (June) Could you create a PR, please?	18:06:44
emily	update eventually merged 3 weeks ago	18:06:56
hexa	yeah, not acceptable	18:07:06
emily	https://github.com/NixOS/nixpkgs/issues/251427 Sadly the package is repeatedly out of date. I would really like to switch to betterbird but as it's internet-facing, timely updates should be ensured. (August 2023)	18:07:52
emily	think it's fair to say that the situation is unlikely to change	18:08:08
hexa	https://github.com/NixOS/nixpkgs/pull/241560#issuecomment-1620795028	18:09:12
hexa	do you remember this one, emily?	18:09:18
aloisw	On a cursory glance, upstream (if that's the correct word here given that it's a patched Thunderbird) maintainance looks kinda okay, but nixpkgs is lagging severely.	18:09:19
emily	upstream is some guy who was banned from Thunderbird development for constantly being uncivil IIRC	18:10:07
emily	but I agree that it seems to meet my basic expectations for backports of upstream browser engine security fixes	18:10:20
emily	so it's ahead of, like, most Firefox forks	18:10:29
emily	In reply to @hexa:lossy.network do you remember this one, emily? right. this is what I was remembering re: stable backports	18:10:47
emily	the commitment is more than I remember, but it doesn't seem to have been fulfilled	18:11:07
emily	currently unfixed on stable that don't look JS-specific: https://bugzilla.mozilla.org/show_bug.cgi?id=1888333 https://bugzilla.mozilla.org/show_bug.cgi?id=1893340 https://bugzilla.mozilla.org/show_bug.cgi?id=1878199 https://bugzilla.mozilla.org/show_bug.cgi?id=1193389 https://bugzilla.mozilla.org/show_bug.cgi?id=1896555 (maybe? "By manipulating the text in an `<input>` tag, an attacker could have caused corrupt memory leading to a potentially exploitable crash." – bug is not public still, lol) https://bugzilla.mozilla.org/buglist.cgi?bug_id=1862809%2C1889355%2C1893388%2C1895123 (also not accesible) uhh more NSS stuff… actually this is too tedious, there's like 3 more point releases left	18:15:36
emily	I think we need to set `knownVulnerabilities` on 24.05 for sure. removal before the 24.11 freeze also seems like a reasonable course of action to me, or we will inevitably end up shipping vulnerable versions to users again within the next 6 months unless someone else wants to be responsible for the package.	18:16:14
emily	actually the NSS stuff might be fine if we have a separate NSS package	18:16:44
emily	and of course it may be hard to impossible to construct an exploit chain for some or all of them without JS	18:16:55
emily	but that is certainly not wholly obvious to me for some of them	18:17:16
Tristan Ross	In reply to @emilazy:matrix.org you'd want to talk to ris Idk who that is	18:19:08
hexa	risicle	18:19:13
hexa	ris_ in this room	18:19:23
emily	also `lib.maintainers.ris`	18:19:39
Tristan Ross	Oh	18:19:43
hexa	In reply to @emilazy:matrix.org actually the NSS stuff might be fine if we have a separate NSS package hm? I maintain nss	18:21:02
Tristan Ross	Time to find the issue I was pinged in relating to what I'm doing lol	18:21:09
emily	I meant that one of the vulns I linked was NSS-related	18:21:13
emily	so it may not apply to us assuming we have a split NSS package that actually gets updates	18:21:23
