NVD Description

Note: Versions mentioned in the description apply only to the upstream rsyslog-gssapi package and not the rsyslog-gssapi package as distributed by RHEL. See How to fix? for RHEL:6 relevant fixed versions and status.

Stack-based buffer overflow in the parseLegacySyslogMsg function in tools/syslogd.c in rsyslogd in rsyslog 4.6.x before 4.6.8 and 5.2.0 through 5.8.4 might allow remote attackers to cause a denial of service (application exit) via a long TAG in a legacy syslog message.
