Description Murray McAllister 2014-02-13 12:35:31 UTC

It was discovered that the Image Resize Filter did not limit the number of resized images per post that a user could send. An attacker could use this flaw to cause a denial of service by submitting a post containing a large number of images to resize:

https://drupal.org/node/2194655

Note that the above advisory states "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."

This issue is resolved in version 6.x-1.14:
