The following versions were EOL at the time the CVE was created but are
known to be affected: from 8.5.0 through 8.5.100, from 7.0.0 through 7.0.109. Other unsupported versions may also be affected.















Users are recommended to upgrade to version 11.0.25, 10.1.58 or 9.0.121, which fixes the issue.
