Affected: < 9.0.9 · >= 10.0 and < 10.0.5

Fixed in: 9.0.9, 10.0.5

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

dnf --showduplicates list bastion sudo dnf downgrade bastion-<VERSION_BEFORE_10.0> sudo dnf versionlock add bastion

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
