Affected: >= 6.x-1.0 and <= 6.x-1.3 · >= 7.x-1.0 and <= 7.x-1.3 · 6.x-1.0 beta1 · 6.x-1.0 rc1 · 6.x-1.x dev · 7.x-1.x dev

Fixed in: newer than 7.x-1.3

Safe to downgrade to: a release before 6.x-1.0

1. Check installed version

apt-cache policy login-security || rpm -q login-security || login-security --version

2. UPGRADE to newer than 7.x-1.3 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade login-security

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade login-security

Note

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

3. If no update is available yet, DOWNGRADE to a release before 6.x-1.0 (Debian / Ubuntu)

apt-cache madison login-security sudo apt install login-security=<VERSION_BEFORE_6.x-1.0> sudo apt-mark hold login-security

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list login-security sudo dnf downgrade login-security-<VERSION_BEFORE_6.x-1.0> sudo dnf versionlock add login-security

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.
