Bug description: big leak with readdir
Description:
------------
I couldnt find anyone who has reported this before, but
there is a big leak with the readdir function.
I was playing with the code and found that you can use is to read the root
directory, or any dir for that matter,
that is a security risk!!!!!!
here is the code -
Hope this helps fix the problem.
Reproduce code:
---------------
function GetDirContents($dir){
ini_set("max_execution_time",10);
if (!is_dir($dir)){die ("OOps");}
if ([EMAIL PROTECTED]($dir)){
while ($file=readdir($root)){
if($file=="." || $file==".."){continue;}
$files[]=$dir.$file;
for($x=0; $x<sizeof($files);$x++)
print $files[$x]<br>";
}
}
return $files;
}
Expected result:
----------------
It will print all of the directories and files
depending on the input.(even the root!!!)
Actual result:
--------------
It will print all of the directories and files
depending on the input.(even the root!!!)
