The remote Oracle Linux host is missing one or more security updates.
From Red Hat Security Advisory 2013:0685 :
Updated perl packages that fix multiple security issues now available
for Red Hat Enterprise Linux 5 and 6.
The Red Hat Security Response Team has rated this update as having
moderate security impact. Common Vulnerability Scoring System (CVSS)
base scores, which give detailed severity ratings, are available for
each vulnerability from the CVE links in the References section.
Perl is a high-level programming language commonly used for system
administration utilities and web programming.
A heap overflow flaw was found in Perl. If a Perl application allowed
user input to control the count argument of the string repeat
operator, an attacker could cause the application to crash or,
potentially, execute arbitrary code with the privileges of the user
running the application. (CVE-2012-5195)
A denial of service flaw was found in the way Perl's rehashing code
implementation, responsible for recalculation of hash keys and
redistribution of hash content, handled certain input. If an attacker
supplied specially crafted input to be used as hash keys by a Perl
application, it could cause excessive memory consumption.
It was found that the Perl CGI module, used to handle Common Gateway
Interface requests and responses, incorrectly sanitized the values for
Set-Cookie and P3P headers. If a Perl application using the CGI module
reused cookies values and accepted untrusted input from web browsers,
a remote attacker could use this flaw to alter member items of the
cookie or add new items. (CVE-2012-5526)
It was found that the Perl Locale::Maketext module, used to localize
Perl applications, did not properly handle backslashes or
fully-qualified method names. An attacker could possibly use this flaw
to execute arbitrary Perl code with the privileges of a Perl
application that uses untrusted Locale::Maketext templates.
Red Hat would like to thank the Perl project for reporting
CVE-2012-5195 and CVE-2013-1667. Upstream acknowledges Tim Brown as
the original reporter of CVE-2012-5195 and Yves Orton as the original
reporter of CVE-2013-1667.
All Perl users should upgrade to these updated packages, which contain
backported patches to correct these issues. All running Perl programs
must be restarted for this update to take effect.
