NVD Description

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

Balabit syslog-ng 2.0.x before 2.0.6 and 2.1.x before 2.1.8 allows remote attackers to cause a denial of service (crash) via a message with a timestamp that does not contain a trailing space, which triggers a NULL pointer dereference.
