Comment 4 Sam James archtester Gentoo Infrastructure gentoo-dev Security 2020-07-01 20:18:34 UTC
Hm. Everything but the original vulnerability was fixed.

Let's use this bug for all the others, then come back and do the original in another bug, I guess.

@maintainer, let us know when ready to stable.
Comment 5 Sam James archtester Gentoo Infrastructure gentoo-dev Security 2020-08-05 18:20:00 UTC
Any objections, or we'll stable?
Comment 6 Sam James archtester Gentoo Infrastructure gentoo-dev Security 2020-08-15 04:05:02 UTC
Please cleanup.
