Subject: Re: PHP and curl open_basedir still bypassable

I got anonyed that the dev php response to this was curl's issue and to turn off curl local file access so here is a hax work around i wrote maybe they will get off there arses and submit something like this in the next release.

in  ext/curl/curl.c, add the following to the function "PHP_FUNCTION(curl_init)".

char *newurl;

<this goes after the argc check>

newurl=estrndup(Z_STRVAL_PP(url), Z_STRLEN_PP(url));
if(strncmp(newurl,file://,7)==0)
    {
    memmove(newurl,newurl+7,strlen(newurl)-7);
    newurl[strlen(newurl)-7+1]='\0';
    if (php_check_open_basedir(newurl TSRMLS_CC))
        {
        RETURN_FALSE;
        }
    }

  As posted in http://www.securitytracker.com/alerts/2004/Oct/1011984.html

  the open_basedir bypass still exists in the php 4.3.10 and curl-7.12.2, anyone seen a patch or anything to get solve this issue?
