menlosecurity email isolation UPGRADE

Affected: >= 2.81.1 and < 2.81.9

Fixed in: 2.81.9

Safe to downgrade to: a release before 2.81.1

1. Check installed version

apt-cache policy email-isolation || rpm -q email-isolation || email-isolation --version

2. UPGRADE to 2.81.9 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade email-isolation

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 2.81.1 (Debian / Ubuntu)

apt-cache madison email-isolation sudo apt install email-isolation=<VERSION_BEFORE_2.81.1> sudo apt-mark hold email-isolation

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

dnf --showduplicates list email-isolation sudo dnf downgrade email-isolation-<VERSION_BEFORE_2.81.1> sudo dnf versionlock add email-isolation

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.
