nsasoft nsauditor UPGRADE

Affected: >= 3.1.2.0 and < 3.2.7

Fixed in: 3.2.7

Safe to downgrade to: a release before 3.1.2.0

1. Check installed version

apt-cache policy nsauditor || rpm -q nsauditor || nsauditor --version

2. UPGRADE to 3.2.7 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade nsauditor

2. UPGRADE (RHEL / Amazon Linux / Fedora)

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 3.1.2.0 (Debian / Ubuntu)

apt-cache madison nsauditor sudo apt install nsauditor=<VERSION_BEFORE_3.1.2.0> sudo apt-mark hold nsauditor

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

dnf --showduplicates list nsauditor sudo dnf downgrade nsauditor-<VERSION_BEFORE_3.1.2.0> sudo dnf versionlock add nsauditor

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.
