nsa ghidra UPGRADE

Affected: >= 10.3 and < 12.2

Fixed in: 12.2

Safe to downgrade to: a release before 10.3

1. Check installed version

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

2. UPGRADE to 12.2 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade ghidra

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 10.3 (Debian / Ubuntu)

apt-cache madison ghidra sudo apt install ghidra=<VERSION_BEFORE_10.3> sudo apt-mark hold ghidra

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

dnf --showduplicates list ghidra sudo dnf downgrade ghidra-<VERSION_BEFORE_10.3> sudo dnf versionlock add ghidra

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.
