Exploitation conditions
No special conditions are documented.
Remediation
Upgrade to 8.2.34, 8.3.35, 8.4.26, 8.5.11 or a later release of your branch. If your branch is end-of-life, move to a supported branch. Distribution packages may carry a backported fix under an older version number; confirm with your vendor's security tracker.
A version number alone cannot prove patch status. Linux distributions and hosting providers often backport security fixes without changing the version. Check your vendor’s changelog.
