firefoxPackages.firefox-esr-52 was removed as it's an unsupported ESR
with open security issues. If you need it because you need to run some
plugins not having been ported to WebExtensions API, import it from an
older nixpkgs checkout still containing it.
There's not really a reason to ship an unsupported ESR variant of
firefox, and if one really needs it, it's also possible to just checkout
an older version of nixpkgs.
These are all based on firefox versions with known vulnerabilities
exploited in the wild.
We seriously shouldn't ship this in nixpkgs, especially not for
sensitive applications as the Tor Browser.
`tor-browser-bundle` is just a wrapper around
`firefoxPackages.tor-browser`, so let's remove it too.
`tor-browser-bundle-bin` is the much safer bet, which is individually
downloaded from `dist.torproject.org` and just `patchelf`-ed locally to
work on NixOS.

It works, but this state is far from ideal: GNU guys update generated source
tarballs very infrequently. Ideally, src needs to be generated by running
makeicecat over firefox src. Will do later.
There have been some more changes to the source tree which broke the
buildconfig patch. This commit adds another patch that can be used for
the future versions. Once all the flavors are based off a new(ish)
firefox release we can remove the old patch.
rust-cbindgen did apply some breaking changes which requires the added
patch in order to compile until a firefox version with the fix gets
released. Firefox 63.0.3 is supposed to carry the required patches. This
should only be required for a short term.
This update bumps the package to the latest stable version containing a
few security fixes:
- CVE-2018-12392: Crash with nested event loops
When manipulating user events in nested loops while opening a document
through script, it is possible to trigger a potentially exploitable
crash due to poor event handling.
- CVE-2018-12393: Integer overflow during Unicode conversion while loading JavaScript
A potential vulnerability was found in 32-bit builds where an integer
overflow during the conversion of scripts to an internal UTF-16
representation could result in allocating a buffer too small for the
conversion. This leads to a possible out-of-bounds write.
Note: 64-bit builds are not vulnerable to this issue.
- CVE-2018-12395: WebExtension bypass of domain restrictions through header rewriting
By rewriting the Host request headers using the webRequest API, a
WebExtension can bypass domain restrictions through domain fronting.
This would allow access to domains that share a host that are
otherwise restricted.
- CVE-2018-12396: WebExtension content scripts can execute in disallowed contexts
A vulnerability where a WebExtension can run content scripts in
disallowed contexts following navigation or other events. This allows
for potential privilege escalation by the WebExtension on sites where
content scripts should not be run.
- CVE-2018-12397: Missing warning prompt when WebExtension requests local file access
A WebExtension can request access to local files without the warning
prompt stating that the extension will "Access your data for all
websites" being displayed to the user. This allows extensions to run
content scripts in local pages without permission warnings when a
local file is opened.
- CVE-2018-12389: Memory safety bugs fixed in Firefox ESR 60.3
Mozilla developers and community members Daniel Veditz and Philipp
reported memory safety bugs present in Firefox ESR 60.2. Some of these
bugs showed evidence of memory corruption and we presume that with
enough effort that some of these could be exploited to run arbitrary
code.
- CVE-2018-12390: Memory safety bugs fixed in Firefox 63 and Firefox ESR 60.3
Mozilla developers and community members Christian Holler, Bob Owen,
Boris Zbarsky, Calixte Denizet, Jason Kratzer, Jed Davis, Taegeon Lee,
Philipp, Ronald Crane, Raul Gurzau, Gary Kwong, Tyson Smith, Raymond
Forbes, and Bogdan Tara reported memory safety bugs present in Firefox
62 and Firefox ESR 60.2. Some of these bugs showed evidence of memory
corruption and we presume that with enough effort that some of these
could be exploited to run arbitrary code.
