We have released a second update this month to address a regression in our earlier release (June 13th). The new versions are .NET 6.0.19 and .NET 7.0.8. The regression is functional and doesn't require action on your part unless you are affected by the issue.
The regression: loading null-password-encrypted PFX certificates can fail unexpectedly for certificates that previously loaded successfully before upgrading to .NET 6.0.18 or 7.0.7.
More Details of this regression are are listed at .NET June OOB Updates
There is no need to install these updates unless you are affected by the functional regression listed at KB5028608.
If you are not affected by the functional regression described above, you can safely remain on 6.0.18 / 7.0.7.
Is 6.0.19 / 7.0.8 a security update?
No. These updates contain no new security fixes beyond what already shipped in 6.0.18 / 7.0.7.
As long as you are running at least 6.0.18 or 7.0.7, you are protected with all of the latest available security fixes.
