Hi Salvatore, thanks for bringing that up. I actually don't think this CVE is valid for ZendFramework 1 (Version < 2). Not only there are big differences in class structure between ZF1 and ZF >= 2.0, but many features have been introduced first in ZF > 2. I see no specific handling for a From header in Zend_Mail_Transport_Sendmail. https://github.com/zendframework/zf1/blob/master/library/Zend/Mail/Transport/Sendmail.php#L128 A user of the library would be able to insert additional parameters, and pass whatever argument to sendmail. But the user would have to care about securing / escaping then. As we currently don't have a package for Zend-Mail, and zendframework is < 2, this bug wouldn't affect Debian. Would love if someone could approve or object my analysis. Cheers Markus Frosch -- [email protected] / [email protected] http://www.lazyfrosch.de
