Background ========== Safe is a Perl module to compile and execute code in restricted compartments. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 perl-core/Safe < 2.27 >= 2.27 2 virtual/perl-Safe < 2.27 >= 2.27 ------------------------------------------------------------------- 2 affected packages ------------------------------------------------------------------- Description =========== Unsafe code evaluation prevents the Safe module from properly restricting the code of implicitly called methods on implicitly blessed objects. Impact ====== 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. Workaround ========== There is no known workaround at this time. 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. References ========== [ 1 ] CVE-2010-1168 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2010-1168 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-201111-09.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users' machines is of utmost importance to us.
