elastic endpoint security UPGRADE

Affected: >= 8.6.0 and < 8.19.13 · >= 9.0.0 and < 9.2.7 · >= 9.3.0 and < 9.3.2

Fixed in: 8.19.13, 9.2.7, 9.3.2

Safe to downgrade to: a release before 8.6.0

1. Check installed version

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

2. UPGRADE to 8.19.13 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade endpoint-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 8.6.0 (Debian / Ubuntu)

apt-cache madison endpoint-security sudo apt install endpoint-security=<VERSION_BEFORE_8.6.0> sudo apt-mark hold endpoint-security

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

dnf --showduplicates list endpoint-security sudo dnf downgrade endpoint-security-<VERSION_BEFORE_8.6.0> sudo dnf versionlock add endpoint-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.
