nodejs node.js DOWNGRADE

Affected: 0.3.2

Fixed in: no fixed release known

Safe to downgrade to: a release before 0.3.2

1. Check installed version

apt-cache policy node.js || rpm -q node.js || node.js --version

2. No fixed release: DOWNGRADE to a release before 0.3.2 (Debian / Ubuntu)

apt-cache madison node.js sudo apt install node.js=<VERSION_BEFORE_0.3.2> sudo apt-mark hold node.js

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

dnf --showduplicates list node.js sudo dnf downgrade node.js-<VERSION_BEFORE_0.3.2> sudo dnf versionlock add node.js

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.

uronode uro node UPGRADE

Affected: <= 1.0.5

Fixed in: newer than 1.0.5

Safe to downgrade to: no unaffected older release

1. Check installed version

apt-cache policy uro-node || rpm -q uro-node || uro-node --version

2. UPGRADE to newer than 1.0.5 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade uro-node

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade uro-node

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

debian debian linux MITIGATE

Affected: 8.0 · 9.0

Fixed in: no fixed release known

Safe to downgrade to: a release before 8.0

Check your OS release

cat /etc/os-release; uname -r

Debian / Ubuntu

sudo apt update && sudo apt full-upgrade

RHEL / Amazon Linux / Fedora

sudo dnf upgrade --refresh

Windows

Install the latest cumulative update from Windows Update

If no patch exists yet

OS downgrades are not safe. Apply the vendor mitigation from the advisory and restrict exposure.
