Mandriva Linux Security Advisory 2013-287 - Drupal core's Image module allows for the on-demand generation of image derivatives. This capability can be abused by requesting a large number of new derivatives which can fill up the server disk space, and which can cause a very high CPU load. Either of these effects may lead to the site becoming unavailable or unresponsive. Drupal's form API has built-in cross-site request forgery 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. 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. Image field descriptions are not properly sanitized before they are printed to HTML, thereby exposing a cross-site scripting vulnerability. 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. The Overlay module displays administrative pages as a layer over the current page , 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. The updated packages has been upgraded to the 7.24 version which is unaffected by these security flaws. Additional apache ACL restrictions has been added to fully conform to the SA-CORE-2013-003 advisory.
