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

This script is Copyright (C) 2012 Tenable Network Security, Inc.


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.
