remote command execution in perl-MailTools

The SuSE Security Team reviewed critical Perl modules, including the Mail::Mailer package. This package contains a security hole which allows remote attackers to execute arbitrary commands in certain circumstances. This is due to the usage of mailx as default mailer which allows commands to be embedded in the mail body. Vulnerable to this attack are custom auto reply programs or spam filters which use Mail::Mailer directly or indirectly.
