View online: https://drupal.org/node/2194655 * Advisory ID: DRUPAL-SA-CONTRIB-2014-017 * Project: Image Resize Filter [1] (third-party module) * Version: 6.x, 7.x * Date: 2014-February-12 * Security risk: Moderately critical [2] * Exploitable from: Remote * Vulnerability: Denial of Service (DOS) -------- DESCRIPTION --------------------------------------------------------- This module enables you to resize images based on the HTML contents of a post. Images with specified height and width properties that differ from the original image result in a resized image being created. The module doesn't limit the number of resized images per post or user, which could allow a user to post a large number of images that need to be resized within a single piece of content. This could cause the server to become overwhelmed by requests to resize images. This vulnerability is mitigated by the fact that an attacker must have a role that allows them to post content that utilizes the image resize filter. -------- CVE IDENTIFIER(S) ISSUED -------------------------------------------- * /A CVE identifier [3] will be requested, and added upon issuance, in accordance with Drupal Security Team processes./ -------- VERSIONS AFFECTED --------------------------------------------------- * Image Resize Filter 6.x-1.x versions prior to 6.x-1.14. * Image Resize Filter 7.x-1.x versions prior to 7.x-1.14.
