apache mina sshd UPGRADE

Affected: >= 2.0.0 and < 2.18.0 · 3.0.0 m1 · 3.0.0 m2 · 3.0.0 m3

Fixed in: 2.18.0

Safe to downgrade to: a release before 2.0.0

1. Check installed version

apt-cache policy mina-sshd || rpm -q mina-sshd || mina-sshd --version

2. UPGRADE to 2.18.0 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade mina-sshd

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade mina-sshd

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 2.0.0 (Debian / Ubuntu)

apt-cache madison mina-sshd sudo apt install mina-sshd=<VERSION_BEFORE_2.0.0> sudo apt-mark hold mina-sshd

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

dnf --showduplicates list mina-sshd sudo dnf downgrade mina-sshd-<VERSION_BEFORE_2.0.0> sudo dnf versionlock add mina-sshd

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.
