aaptjs project aaptjs DOWNGRADE

Affected: 1.3.1

Fixed in: no fixed release known

Safe to downgrade to: a release before 1.3.1

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 1.3.1 (Debian / Ubuntu)

apt-cache madison aaptjs sudo apt install aaptjs=<VERSION_BEFORE_1.3.1> sudo apt-mark hold aaptjs

2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list aaptjs sudo dnf downgrade aaptjs-<VERSION_BEFORE_1.3.1> sudo dnf versionlock add aaptjs

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.
