A 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. (CVE-2006-5178)
Because the design flaw cannot be solved it is strongly recommended to disable the symlink() function if you are using the open_basedir feature. You can achieve that by adding symlink to the list of disabled functions within your php.ini: disable_functions=...,symlink
The updated packages do not alter the system php.ini.
Updated packages have been patched to correct the CVE-2006-4625 issue.
Users must restart Apache for the changes to take effect.
