CVE-2006-5178
PHP Symlink Open_Basedir Bypass
Description
Race condition in the symlink function in PHP 5.1.6 and earlier allows local users to bypass the open_basedir restriction by using a combination of symlink, mkdir, and unlink functions to change the file path after the open_basedir check and before the file is opened by the underlying system, as demonstrated by symlinking a symlink into a subdirectory, to point to a parent directory via .. (dot dot) sequences, and then unlinking the resulting symlink.

When PHP's open_basedir restriction is set, PHP disables the realpath cache for security reasons. This may hurt your application performance. The realpath_turbo PHP extension re-enables the realpath cache. Warning: This could be a security problem in your environment! Please read the README for further information.
