jetico bcwipe UPGRADE

Affected: >= 2.0 and <= 2.35.1 · 1.0.7

Fixed in: newer than 2.35.1

Safe to downgrade to: a release before 1.0.7

1. Check installed version

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

2. UPGRADE to newer than 2.35.1 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade bcwipe

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 1.0.7 (Debian / Ubuntu)

apt-cache madison bcwipe sudo apt install bcwipe=<VERSION_BEFORE_1.0.7> sudo apt-mark hold bcwipe

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

dnf --showduplicates list bcwipe sudo dnf downgrade bcwipe-<VERSION_BEFORE_1.0.7> sudo dnf versionlock add bcwipe

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.
