The remote Oracle Linux host is missing one or more security updates.
From Red Hat Security Advisory 2011:1247 :
Updated rsyslog packages that fix one security issue are now available
for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having
moderate security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from
the CVE link in the References section.
The rsyslog packages provide an enhanced, multi-threaded syslog daemon
that supports MySQL, syslog/TCP, RFC 3195, permitted sender lists,
filtering on any message part, and fine grained output format control.
A two byte buffer overflow flaw was found in the rsyslog daemon's
parseLegacySyslogMsg function. An attacker able to submit log messages
to rsyslogd could use this flaw to crash the daemon. (CVE-2011-3200)
All rsyslog users should upgrade to these updated packages, which
contain a backported patch to correct this issue. After installing
this update, the rsyslog daemon will be restarted automatically.
