  <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 "&gt;=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 "&gt;=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.
