NVD Description

Note: Versions mentioned in the description apply only to the upstream rsyslog package and not the rsyslog package as distributed by Debian. See How to fix? for Debian:14 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 multiple rulesets were used and some output batches contained messages belonging to more than one ruleset. A local attacker could cause denial of the rsyslogd daemon service via a log message belonging to more than one ruleset
