CWE-772  (opens in a new tab)

How to fix?

Upgrade Echo:latest rsyslog to version 5.7.6-1 or higher.

NVD Description

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

A memory leak in rsyslog before 5.7.6 was found in the way deamon processed log messages are logged when $RepeatedMsgReduction was enabled. A local attacker could use this flaw to cause a denial of the rsyslogd daemon service by crashing the service via a sequence of repeated log messages sent within short periods of time.
