How to fix?

Upgrade Alpine:3.20 syslog-ng to version 3.38.1-r0 or higher.

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 Alpine. See How to fix? for Alpine:3.20 relevant fixed versions and status.

An integer overflow in the RFC3164 parser in One Identity syslog-ng 3.0 through 3.37 allows remote attackers to cause a Denial of Service via crafted syslog input that is mishandled by the tcp or network function. syslog-ng Premium Edition 7.0.30 and syslog-ng Store Box 6.10.0 are also affected.
