Check your OS release

cat /etc/os-release; uname -r

Debian / Ubuntu

sudo apt update && sudo apt full-upgrade

RHEL / Amazon Linux / Fedora

sudo dnf upgrade --refresh

Install the latest cumulative update from Windows Update

If no patch exists yet

OS downgrades are not safe. Apply the vendor mitigation from the advisory and restrict exposure.

arubanetworks sd-wan UPGRADE

Affected: >= 8.6.0.4-2.2.0.0 and <= 8.6.0.4-2.2.0.7 · >= 8.7.0.0-2.3.0.0 and <= 8.7.0.0-2.3.0.9

Fixed in: newer than 8.7.0.0-2.3.0.9

Safe to downgrade to: a release before 8.6.0.4-2.2.0.0

1. Check installed version

apt-cache policy sd-wan || rpm -q sd-wan || sd-wan --version

2. UPGRADE to newer than 8.7.0.0-2.3.0.9 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade sd-wan

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade sd-wan

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 8.6.0.4-2.2.0.0 (Debian / Ubuntu)

apt-cache madison sd-wan sudo apt install sd-wan=<VERSION_BEFORE_8.6.0.4-2.2.0.0> sudo apt-mark hold sd-wan

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

dnf --showduplicates list sd-wan sudo dnf downgrade sd-wan-<VERSION_BEFORE_8.6.0.4-2.2.0.0> sudo dnf versionlock add sd-wan

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.
