Scientific Linux Security Update : perl on SL3.x, SL4.x i386/x86_64

high Nessus Plugin ID 60800

Language:

Synopsis

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

Description

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)

These packages upgrade the Safe extension module to version 2.27.
Refer to the Safe module's Changes file at the following link for a full list of changes.
http://cpansearch.perl.org/src/RGARCIA/Safe-2.27/Changes

All applications using the Safe extension module must be restarted for this update to take effect.

Solution
