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.
