<title>Perl Safe module: Arbitrary Perl code injection</title>
<synopsis>The Safe module for Perl does not properly restrict code, allowing
a remote attacker to execute arbitrary Perl code outside of a restricted
compartment.

<background>
<p>Safe is a Perl module to compile and execute code in restricted
compartments.
</p>
</background>
<description>
<p>Unsafe code evaluation prevents the Safe module from properly
restricting the code of implicitly called methods on implicitly blessed
objects.
</p>
</description>
<impact type="normal">
<p>A remote attacker could entice a user to load a specially crafted Perl
script, resulting in execution arbitrary Perl code outside of a
restricted compartment.
</p>
</impact>
<workaround>
<p>There is no known workaround at this time.</p>
</workaround>
<resolution>
<p>All users of the standalone Perl Safe module should upgrade to the
latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=perl-core/Safe-2.27"
</code>
<p>All users of the Safe module bundled with Perl should upgrade to the
latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=virtual/perl-Safe-2.27"
</code>
<p>NOTE: This is a legacy GLSA. Updates for all affected architectures are
available since July 18, 2010. It is likely that your system is already
no longer affected by this issue.
