rusqlite project rusqlite UPGRADE

Affected: >= 0.25.0 and < 0.25.4 · >= 0.26.0 and < 0.26.2

Fixed in: 0.25.4, 0.26.2

Safe to downgrade to: a release before 0.25.0

1. Check installed version

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

2. UPGRADE to 0.25.4 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade rusqlite

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 0.25.0 (Debian / Ubuntu)

apt-cache madison rusqlite sudo apt install rusqlite=<VERSION_BEFORE_0.25.0> sudo apt-mark hold rusqlite

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

dnf --showduplicates list rusqlite sudo dnf downgrade rusqlite-<VERSION_BEFORE_0.25.0> sudo dnf versionlock add rusqlite

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.
