PHP Other Vulnerability - CVE-2006-1015

Argument injection vulnerability in certain PHP 3.x 4.x and 5.x applications when used with sendmail and when accepting remote input for the additional_parameters argument to the mail function allows remote attackers to read and create arbitrary files via the sendmail -C and -X arguments. 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.
