How to fix?

Upgrade Echo:latest fetchmail to version 6.3.8-8 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream fetchmail package and not the fetchmail package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

sink.c in fetchmail before 6.3.9 allows context-dependent attackers to cause a denial of service (NULL dereference and application crash) by refusing certain warning messages that are sent over SMTP.
