Timeline

paloaltonetworks globalprotect UPGRADE
Affected: >= 6.0.0 and < 6.0.11 · >= 6.3.0 and < 6.3.3 · 6.3.3 · 6.3.3 h1
Fixed in: 6.0.11, 6.3.3
Safe to downgrade to: a release before 6.0.0
1. Check installed version
apt-cache policy globalprotect || rpm -q globalprotect || globalprotect --version
2. UPGRADE to 6.0.11 (Debian / Ubuntu)
sudo apt update && sudo apt install --only-upgrade globalprotect
2. UPGRADE (RHEL / Amazon Linux / Fedora)
sudo dnf upgrade globalprotect
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 6.0.0 (Debian / Ubuntu)
apt-cache madison globalprotect sudo apt install globalprotect=<VERSION_BEFORE_6.0.0> sudo apt-mark hold globalprotect
3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)
dnf --showduplicates list globalprotect sudo dnf downgrade globalprotect-<VERSION_BEFORE_6.0.0> sudo dnf versionlock add globalprotect
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.
