Timeline

ibm security verify access UPGRADE
Affected: >= 10.0.0 and < 10.0.9.3
Fixed in: 10.0.9.3
Safe to downgrade to: a release before 10.0.0
1. Check installed version
apt-cache policy security-verify-access || rpm -q security-verify-access || security-verify-access --version
2. UPGRADE to 10.0.9.3 (Debian / Ubuntu)
sudo apt update && sudo apt install --only-upgrade security-verify-access
2. UPGRADE (RHEL / Amazon Linux / Fedora)
sudo dnf upgrade security-verify-access
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 10.0.0 (Debian / Ubuntu)
apt-cache madison security-verify-access sudo apt install security-verify-access=<VERSION_BEFORE_10.0.0> sudo apt-mark hold security-verify-access
3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)
dnf --showduplicates list security-verify-access sudo dnf downgrade security-verify-access-<VERSION_BEFORE_10.0.0> sudo dnf versionlock add security-verify-access
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.
