spip spip UPGRADE

Affected: >= 4.4.10 and < 4.4.13

Fixed in: 4.4.13

Safe to downgrade to: a release before 4.4.10

1. Check installed version

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

2. UPGRADE to 4.4.13 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade spip

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade spip

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 4.4.10 (Debian / Ubuntu)

apt-cache madison spip sudo apt install spip=<VERSION_BEFORE_4.4.10> sudo apt-mark hold spip

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

dnf --showduplicates list spip sudo dnf downgrade spip-<VERSION_BEFORE_4.4.10> sudo dnf versionlock add spip

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.
