libdwarf project libdwarf UPGRADE

Affected: >= 0.1.0 and < 0.9.2

Fixed in: 0.9.2

Safe to downgrade to: a release before 0.1.0

1. Check installed version

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

2. UPGRADE to 0.9.2 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade libdwarf

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 0.1.0 (Debian / Ubuntu)

apt-cache madison libdwarf sudo apt install libdwarf=<VERSION_BEFORE_0.1.0> sudo apt-mark hold libdwarf

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

dnf --showduplicates list libdwarf sudo dnf downgrade libdwarf-<VERSION_BEFORE_0.1.0> sudo dnf versionlock add libdwarf

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.
