Synopsis

The remote Red Hat host is missing one or more security updates for perl.

Description

The remote Redhat Enterprise Linux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2010:0457 advisory.

Perl is a high-level programming language commonly used for system administration utilities and web programming. The Safe extension module allows users to compile and execute Perl code in restricted compartments.

The Safe module did not properly restrict the code of implicitly called methods (such as DESTROY and AUTOLOAD) on implicitly blessed objects returned as a result of unsafe code evaluation. These methods could have been executed unrestricted by Safe when such objects were accessed or destroyed. A specially-crafted Perl script executed inside of a Safe compartment could use this flaw to bypass intended Safe module restrictions. (CVE-2010-1168)

The Safe module did not properly restrict code compiled in a Safe compartment and executed out of the compartment via a subroutine reference returned as a result of unsafe code evaluation. A specially-crafted Perl script executed inside of a Safe compartment could use this flaw to bypass intended Safe module restrictions, if the returned subroutine reference was called from outside of the compartment. (CVE-2010-1447)

Red Hat would like to thank Tim Bunce for responsibly reporting the CVE-2010-1168 and CVE-2010-1447 issues. Upstream acknowledges Nick Cleaton as the original reporter of CVE-2010-1168, and Tim Bunce and Rafal Garcia-Suarez as the original reporters of CVE-2010-1447.

These packages upgrade the Safe extension module to version 2.27. Refer to the Safe module's Changes file, linked to in the References, for a full list of changes.

Users of perl are advised to upgrade to these updated packages, which correct these issues. All applications using the Safe extension module must be restarted for this update to take effect.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL perl package based on the guidance in RHSA-2010:0457.
