PHP Other Vulnerability - CVE-2006-1014

Argument injection vulnerability in certain PHP 4.x and 5.x applications when used with sendmail and when accepting remote input for the additional_parameters argument to the mb_send_mail function allows context-dependent attackers to read and create arbitrary files by providing extra -C and -X arguments to sendmail. NOTE: it could be argued that this is a class of technology-specific vulnerability instead of a particular instance if so then this should not be included in CVE.
