versa-networks sase client UPGRADE

Affected: >= 7.8.7 and < 7.9.5

Fixed in: 7.9.5

Safe to downgrade to: a release before 7.8.7

1. Check installed version

apt-cache policy sase-client || rpm -q sase-client || sase-client --version

2. UPGRADE to 7.9.5 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade sase-client

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade sase-client

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 7.8.7 (Debian / Ubuntu)

apt-cache madison sase-client sudo apt install sase-client=<VERSION_BEFORE_7.8.7> sudo apt-mark hold sase-client

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

dnf --showduplicates list sase-client sudo dnf downgrade sase-client-<VERSION_BEFORE_7.8.7> sudo dnf versionlock add sase-client

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.
