gnu binutils DOWNGRADE

Affected: 2.32

Fixed in: no fixed release known

Safe to downgrade to: a release before 2.32

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 2.32 (Debian / Ubuntu)

apt-cache madison binutils sudo apt install binutils=<VERSION_BEFORE_2.32> sudo apt-mark hold binutils

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

dnf --showduplicates list binutils sudo dnf downgrade binutils-<VERSION_BEFORE_2.32> sudo dnf versionlock add binutils

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.

netapp element software MITIGATE

Affected: all versions

Fixed in: no fixed release known

Safe to downgrade to: no unaffected older release

1. Check installed version

apt-cache policy element-software || rpm -q element-software || element-software --version

No fixed or unaffected release known

Apply the vendor mitigation from the advisory, disable the affected feature, or restrict network access.

canonical ubuntu linux MITIGATE

Affected: 18.04

Fixed in: no fixed release known

Safe to downgrade to: a release before 18.04

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

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

f5 traffix signaling delivery controller UPGRADE

Affected: >= 5.0.0 and <= 5.1.0

Fixed in: newer than 5.1.0

Safe to downgrade to: a release before 5.0.0

1. Check installed version

apt-cache policy traffix-signaling-delivery-controller || rpm -q traffix-signaling-delivery-controller || traffix-signaling-delivery-controller --version

2. UPGRADE to newer than 5.1.0 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade traffix-signaling-delivery-controller

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade traffix-signaling-delivery-controller

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 5.0.0 (Debian / Ubuntu)

apt-cache madison traffix-signaling-delivery-controller sudo apt install traffix-signaling-delivery-controller=<VERSION_BEFORE_5.0.0> sudo apt-mark hold traffix-signaling-delivery-controller

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

dnf --showduplicates list traffix-signaling-delivery-controller sudo dnf downgrade traffix-signaling-delivery-controller-<VERSION_BEFORE_5.0.0> sudo dnf versionlock add traffix-signaling-delivery-controller

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.
