Bug description: realpath() returns empty string when working directory is under a symbolic link
/opt/apache/htdocs is the Document Root for Apache.
/opt/apache/htdocs/directory is a symbolic link that points to /home/morespace/directory. Document
/home/morespace/directory/username/index.php contains the code:
$RealPath = realpath(".");
if (!stristr($RealPath, $UserName)){
echo "This directory does not belong to you. Attempt has been logged.";
session_destroy();
exit;
}
This code always fails because realpath(".") returns an empty string.
