By Drupal Security Team on
  • Advisory ID: DRUPAL-SA-CONTRIB-2014-017
  • Project: Image Resize Filter (third-party module)
  • Version: 6.x, 7.x
  • Date: 2014-February-12
  • Security risk: Moderately critical
  • 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.
