Upgrade Echo:latest 389-ds-base to version 1.3.7.9-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream 389-ds-base package and not the 389-ds-base package as distributed by Echo.
See How to fix? for Echo:latest relevant fixed versions and status.
It was found that 389-ds-base since 1.3.6.1 up to and including 1.4.0.3 did not always handle internal hash comparison operations correctly during the authentication process. A remote, unauthenticated attacker could potentially use this flaw to bypass the authentication process under very rare and specific circumstances.
