Race condition in the rmtree and remove_tree functions allows attackers to set the mode on arbitrary files via vectors involving directory-permission loosening logic.
The rmtree function in lib/File/Path.pm in Perl 5.10 does not properly check permissions before performing a chmod, which allows local users to modify the permissions of arbitrary files via a symlink attack, a different vulnerability than CVE-2005-0448 and CVE-2004-0452.
Problem on Windows where c:\path\to\dir was not considered to be underneath C:/Path/To (issues of directory separators and case sensitivity). As reported in smoke report http://www.nntp.perl.org/group/perl.cpan.testers/2008/05/msg1435813.html
Changes for version 2.06_01 - 2008-05-10
Close directory handle in t/Path.t with closedir (close is close but incorrect). Problem identified with Strawberry Perl.
