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.

lib/logmatcher.c in Balabit syslog-ng before 3.2.4, when the global flag is set and when using PCRE 8.12 and possibly other versions, allows remote attackers to cause a denial of service (memory consumption) via a message that does not match a regular expression.
