libxmljs project libxmljs DOWNGRADE

Affected: 1.0.11

Fixed in: no fixed release known

Safe to downgrade to: a release before 1.0.11

1. Check installed version

npm ls libxmljs

2. No fixed release: DOWNGRADE to a release before 1.0.11

npm view libxmljs versions npm install libxmljs@"<1.0.11"

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.
