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.
