sonicwall analyzer UPGRADE

Affected: >= 7.0 and <= 7.2 · >= 8.1 and <= 8.4

Fixed in: newer than 8.4

Safe to downgrade to: a release before 7.0

1. Check installed version

apt-cache policy analyzer || rpm -q analyzer || analyzer --version

2. UPGRADE to newer than 8.4 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade analyzer

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade analyzer

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 7.0 (Debian / Ubuntu)

apt-cache madison analyzer sudo apt install analyzer=<VERSION_BEFORE_7.0> sudo apt-mark hold analyzer

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

dnf --showduplicates list analyzer sudo dnf downgrade analyzer-<VERSION_BEFORE_7.0> sudo dnf versionlock add analyzer

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.
