cimtechniques cimscan UPGRADE

Affected: >= 6.0.5814 and <= 6.2

Fixed in: newer than 6.2

Safe to downgrade to: a release before 6.0.5814

1. Check installed version

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

2. UPGRADE to newer than 6.2 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade cimscan

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 6.0.5814 (Debian / Ubuntu)

apt-cache madison cimscan sudo apt install cimscan=<VERSION_BEFORE_6.0.5814> sudo apt-mark hold cimscan

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

dnf --showduplicates list cimscan sudo dnf downgrade cimscan-<VERSION_BEFORE_6.0.5814> sudo dnf versionlock add cimscan

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.
