Synopsis:	Moderate: perl security update
Issue date:	2010-06-07
CVE Names:	CVE-2010-1168 CVE-2010-1447

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.

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