gnu libredwg UPGRADE

Affected: >= 0.13.3.7571 and <= 0.13.3.7835

Fixed in: newer than 0.13.3.7835

Safe to downgrade to: a release before 0.13.3.7571

1. Check installed version

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

2. UPGRADE to newer than 0.13.3.7835 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade libredwg

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 0.13.3.7571 (Debian / Ubuntu)

apt-cache madison libredwg sudo apt install libredwg=<VERSION_BEFORE_0.13.3.7571> sudo apt-mark hold libredwg

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

dnf --showduplicates list libredwg sudo dnf downgrade libredwg-<VERSION_BEFORE_0.13.3.7571> sudo dnf versionlock add libredwg

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.
