Updated drupal package fixes security vulnerabilities

Drupal’s form API has built-in cross-site request forgery (CSRF) validation, and also allows any module to perform its own validation on the form. In certain common cases, form validation functions may execute unsafe operations (CVE-2013-6385). Drupal core directly used the mt_rand() pseudorandom number generator for generating security related strings used in several core modules. It was found that brute force tools could determine the seeds making these strings predictable under certain circumstances (CVE-2013-6386). Image field descriptions are not properly sanitized before they are printed to HTML, thereby exposing a cross-site scripting vulnerability (CVE-2013-6387). A cross-site scripting vulnerability was found in the Color module. A malicious attacker could trick an authenticated administrative user into visiting a page containing specific JavaScript that could lead to a reflected cross-site scripting attack via JavaScript execution in CSS (CVE-2013-6388). The Overlay module displays administrative pages as a layer over the current page (using JavaScript), rather than replacing the page in the browser window. The Overlay module did not sufficiently validate URLs prior to displaying their contents, leading to an open redirect vulnerability (CVE-2013-6389).
