Public bug reported: Impact ------ mozjs102 is the SpiderMonkey JavaScript engine from Firefox ESR. It is used by gjs to power GNOME Shell and some GNOME apps.
There are new Firefox 102 ESR releases monthly until the end of August. https://whattrainisitnow.com/calendar/ 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/mfsa2023-23/ and found two CVEs CVE-2023-37202: Potential use-after-free from compartment mismatch in SpiderMonkey CVE-2023-37211 Test Case --------- https://wiki.ubuntu.com/DesktopTeam/TestPlans/gjs Additionally, mozjs102 has build tests. mozjs102 does not have autopkgtests of its own but it triggers the gjs autopkgtests. Security Sponsoring ------------------- sudo apt install git-buildpackage mkdir tarballs; cd ../tarballs pull-lp-source mozjs102 mantic # That avoids needing to recreate the original tarball from pristine-tar which takes a while. Also, running lintian takes a while. cd .. gbp clone https://salsa.debian.org/gnome-team/mozjs cd mozjs git checkout ubuntu/102/lunar gbp buildpackage --git-builder="debuild --no-lintian -S -nc" --git-tarball-dir=../tarballs git checkout ubuntu/102/kinetic gbp buildpackage --git-builder="debuild --no-lintian -S -nc" --git-tarball-dir=../tarballs git checkout ubuntu/102/jammy gbp buildpackage --git-builder="debuild --no-lintian -S -nc" --git-tarball-dir=../tarballs Initial Testing Done -------------------- I built the package locally. I installed the library package on Ubuntu 23.04 and successfully completed the Test Case. Other Info ---------- It is believed that the only thing using mozjs102 in Ubuntu 22.04 LTS is actually cjs in Linux Mint 21.2 (in Beta testing). It has been proposed to switch Ubuntu's gjs to use it there also but that is currently on hold (benefit/risk analysis).
