opensuse opensuse MITIGATE

Affected: 13.1 · 13.2

Fixed in: no fixed release known

Safe to downgrade to: a release before 13.1

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

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

mega-nerd libsndfile DOWNGRADE

Affected: 1.0.25

Fixed in: no fixed release known

Safe to downgrade to: a release before 1.0.25

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 1.0.25 (Debian / Ubuntu)

apt-cache madison libsndfile sudo apt install libsndfile=<VERSION_BEFORE_1.0.25> sudo apt-mark hold libsndfile

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

dnf --showduplicates list libsndfile sudo dnf downgrade libsndfile-<VERSION_BEFORE_1.0.25> sudo dnf versionlock add libsndfile

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.
