steve j baker plib DOWNGRADE

Affected: 1.8.5

Fixed in: no fixed release known

Safe to downgrade to: a release before 1.8.5

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 1.8.5 (Debian / Ubuntu)

apt-cache madison plib sudo apt install plib=<VERSION_BEFORE_1.8.5> sudo apt-mark hold plib

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

dnf --showduplicates list plib sudo dnf downgrade plib-<VERSION_BEFORE_1.8.5> sudo dnf versionlock add plib

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.

Public exploits and detection
