Gentoo GLSA-201111-09 Normal: Perl Safe Module Code Execution Risk
gentoo
November 20, 2011
The Safe module for Perl does not properly restrict code, allowing a remote attacker to execute arbitrary Perl code outside of a restricted compartment
Summary
Unsafe code evaluation prevents the Safe module from properly restricting the code of implicitly called methods on implicitly blessed objects.
Topics Covered
Resolution
All users of the standalone Perl Safe module should upgrade to the
latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=perl-core/Safe-2.27"
All users of the Safe module bundled with Perl should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=virtual/perl-Safe-2.27"
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.
