paloaltonetworks cortex xdr agent UPGRADE

Affected: >= 8.7.0 and < 8.7.101 · 7.9 · 8.3 · 8.9.0 · 9.0.0

Fixed in: 8.7.101

Safe to downgrade to: a release before 7.9

1. Check installed version

apt-cache policy cortex-xdr-agent || rpm -q cortex-xdr-agent || cortex-xdr-agent --version

2. UPGRADE to 8.7.101 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade cortex-xdr-agent

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade cortex-xdr-agent

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 7.9 (Debian / Ubuntu)

apt-cache madison cortex-xdr-agent sudo apt install cortex-xdr-agent=<VERSION_BEFORE_7.9> sudo apt-mark hold cortex-xdr-agent

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

dnf --showduplicates list cortex-xdr-agent sudo dnf downgrade cortex-xdr-agent-<VERSION_BEFORE_7.9> sudo dnf versionlock add cortex-xdr-agent

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.
