Somehow this ended up in the wrong place.

Thanks, how is this going? Is there any vulnerable version in tree?

I suppose that summary should have a "<" at the beginning which says that we need to clean up or mask vulnerable versions.

@Maintainers could you please confirm?

Nope, these are the vulnerable versions.

We are going to stabilize 6.4.0 soon, until then we just have to wait here.

5.4.0* will be masked sometime afterwards (for different reasons), 6.3 removed. No further cleanup.
Comment 6 Aaron Bauman (RETIRED) gentoo-dev 2019-08-10 17:28:30 UTC
please extend mask
Comment 7 Aaron Bauman (RETIRED) gentoo-dev 2020-05-02 02:40:06 UTC
mask is good.
