Please file a separate bug for that so we can stablize packages independently.

Google does not publish security advisories for the beta channel, and we never mark it stable.

Yes, beta is vulnerable. Fix is:



@ Maintainer(s): Please don't forget to bump beta channel to >=73.0.3683.60.

You don't need to remind me how to maintain a package.
Comment 10 Michael Palimaka (kensington) gentoo-dev 2019-03-11 06:52:53 UTC
Since bug #679650 has been filed to track dev-qt/qtwebgine, I will remove qt@ from CC here.
Comment 11 Mike Gilbert gentoo-dev 2019-03-17 02:50:30 UTC
www-client/chromium-73.0.3683.75 has been added to the repo and will be stabilized under bug 680242.
