Oracle Linux 6 : perl (ELSA-2011-1424)

high Nessus Plugin ID 68383


The remote Oracle Linux host is missing one or more security updates.


From Red Hat Security Advisory 2011:1424 :

Updated perl packages that fix two security issues are now available for Red Hat Enterprise Linux 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-based buffer overflow flaw was found in the way Perl decoded Unicode strings. An attacker could create a malicious Unicode string that, when decoded by a Perl program, would cause the program to crash or, potentially, execute arbitrary code with the permissions of the user running the program. (CVE-2011-2939)

It was found that the 'new' constructor of the Digest module used its argument as part of the string expression passed to the eval() function. An attacker could possibly use this flaw to execute arbitrary Perl code with the privileges of a Perl program that uses untrusted input as an argument to the constructor. (CVE-2011-3597)

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.


Update the affected perl packages.
