Updated perl and perl-PathTools packages fix security vulnerability
It was reported that File::Spec::canonpath() routine returns untainted strings even if passed tainted input. This defect undermines the guarantee of taint propagation, which is sometimes used to ensure that unvalidated user input does not reach sensitive code (CVE-2015-8607).
