cybereason endpoint detection and response UPGRADE

Affected: < 19.1.282 · >= 19.2.0 and < 19.2.182 · >= 20.1.0 and < 20.1.343 · 20.2.0

Fixed in: 19.1.282, 19.2.182, 20.1.343

Safe to downgrade to: a release before 19.2.0

1. Check installed version

apt-cache policy endpoint-detection-and-response || rpm -q endpoint-detection-and-response || endpoint-detection-and-response --version

2. UPGRADE to 19.1.282 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade endpoint-detection-and-response

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade endpoint-detection-and-response

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 19.2.0 (Debian / Ubuntu)

apt-cache madison endpoint-detection-and-response sudo apt install endpoint-detection-and-response=<VERSION_BEFORE_19.2.0> sudo apt-mark hold endpoint-detection-and-response

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

dnf --showduplicates list endpoint-detection-and-response sudo dnf downgrade endpoint-detection-and-response-<VERSION_BEFORE_19.2.0> sudo dnf versionlock add endpoint-detection-and-response

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.
