Affected: < 7.146.35 · >= 7.161.0 and < 7.161.16

Fixed in: 7.146.35, 7.161.16

Safe to downgrade to: a release before 7.161.0

1. Check installed version

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

2. UPGRADE to 7.146.35 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

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 7.161.0 (Debian / Ubuntu)

apt-cache madison artifactory sudo apt install artifactory=<VERSION_BEFORE_7.161.0> sudo apt-mark hold artifactory

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

dnf --showduplicates list artifactory sudo dnf downgrade artifactory-<VERSION_BEFORE_7.161.0> sudo dnf versionlock add artifactory

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.
