MEDIUM 6.5UPGRADEMITIGATE

CVE-2022-1348 is a medium-severity flaw (CVSS 6.5) affecting logrotate, fedora. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

A vulnerability was found in logrotate in how the state file is created. The state file is used to prevent parallel executions of multiple instances of logrotate by acquiring and releasing a file lock. When the state file does not exist, it is created with world-readable permission, allowing an unprivileged user to lock the state file, stopping any rotation. This flaw affects logrotate versions before 3.20.0.

Why this priority

No elevated risk signals yet

logrotate project logrotate UPGRADE

Affected: >= 3.17.0 and < 3.20.0

Fixed in: 3.20.0

Safe to downgrade to: a release before 3.17.0

1. Check installed version

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

2. UPGRADE to 3.20.0 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade logrotate

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 3.17.0 (Debian / Ubuntu)

apt-cache madison logrotate sudo apt install logrotate=<VERSION_BEFORE_3.17.0> sudo apt-mark hold logrotate

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

dnf --showduplicates list logrotate sudo dnf downgrade logrotate-<VERSION_BEFORE_3.17.0> sudo dnf versionlock add logrotate

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.
