GENTOO LINUX SECURITY ANNOUNCEMENT 200212-6
--------------------------------------------------------------------

PACKAGE : perl
SUMMARY : broken safe compartment
DATE    : 2002-12-20 14:12 UTC
EXPLOIT : local

--------------------------------------------------------------------

Quote from http://use.perl.org/articles/02/10/06/1118222.shtml?tid=5

"A security hole has been discovered in Safe.pm. When a Safe 
compartment has already been used, there's no guarantee that it's safe 
any longer, because there's a way for code executed within the Safe 
compartment to alter its operation mask. (Thus, programs that use a 
Safe compartment only once aren't affected by this bug"

SOLUTION

It is recommended that all Gentoo Linux users who are running
sys-devel/perl-5.6.1-r9 or sys-devel/5.8.0-r5 and earlier update their 
systems as follows:

emerge rsync
emerge perl
emerge clean

ALTERNATIVE SOLUTION

If you don't want to or can't upgrade your perl package right away,
you can emerge dev-perl/Safe to accomplish the same solution as above.
