A flaw was found in the Archive_Tar package. Archive_Tar could allow a remote attacker to traverse directories on the system caused by inadequate checking of symbolic links. An attacker could send a specially-crafted URL request to the Tar.php script containing "dot dot" sequences (/../) to modify arbitrary files on the system.
