** Description changed:
Impact
------
GNOME Shell uses the SpiderMonkey JavaScript engine from Firefox ESR (mozjs).
Firefox 92 ESR has reached end of life; therefore, we should switch to the 102
ESR series for security updates for the next year.
This requires updating gjs from 1.72 to 1.74 from GNOME 43, as packaged
in Ubuntu 22.10.
This will be done as a Security Update.
Updating mozjs in stable Ubuntu releases was recommended when Ubuntu
first switched back to GNOME, but this is the first time it's been done.
Security Impact
---------------
I looked through
https://github.com/mozilla/gecko-dev/commits/esr102/js
and searched for referenced bug numbers in
https://www.mozilla.org/en-US/security/advisories/
for Firefox ESR releases since Ubuntu's 91.10
and found one CVE. Also, there's the vague Mozilla Bug 1771084 (no CVE
issued) mentioned at
https://www.mozilla.org/en-US/security/advisories/mfsa2022-24/
Uploaded Packages
-----------------
We will introduce mozjs102, a new source package for Ubuntu 22.04 LTS, being
careful to publish it in main, not universe.
And we'll update gjs.
No other packages need to be updated for this change.
mozjs91 will remain in Ubuntu 22.04 LTS (source package removals are
generally not possible), but nothing else in Ubuntu uses it.
Test Case
---------
https://wiki.ubuntu.com/DesktopTeam/TestPlans/gjs
- Prerequisite
- ------------
- We need to get mozjs102 on the i386 whitelist for Ubuntu 22.04 LTS
-
Security Sponsoring
-------------------
sudo apt install git-buildpackage
gbp clone https://salsa.debian.org/gnome-team/gjs
cd gjs
git checkout ubuntu/jammy
gbp buildpackage --git-builder="debuild -S -nc"
mkdir -p tarballs; cd tarballs
pull-lp-source mozjs102 kinetic
cd ..
gbp clone https://salsa.debian.org/gnome-team/mozjs
cd mozjs
git checkout ubuntu/102/jammy
gbp buildpackage --git-builder="debuild --no-lintian -S -nc"
--git-tarball-dir=../tarballs
# That avoids needing to recreate the original tarball from pristine-tar
which takes a while. Also, running lintian takes a while.
Initial Testing Done
--------------------
I built the packages in my PPA.
- Only issue is that mozjs102 was not built for i386 but it's needed.
I installed the packages on Ubuntu 22.04 LTS and successfully completed the
Test Case.
