Thanks for the problem report. We can reproduce it and will have a patch to fix it in GIT master branch @ https://github.com/ImageMagick/ImageMagick later today. The patch will be available in the beta releases of ImageMagick @ http://www.imagemagick.org/download/beta/ by sometime tomorrow. |

This was assigned CVE-2019-13299. |
|
Hi, I noticed that the fixing commit isn't included in the releases, only in master. All versions are still valnurable if I download the files from GitHub? |
|
The patch is in the current release. Download the latest release, run your POC, if it fails, let us know. |
|
The POC is no longer triggered suggesting our patch mitigated the vulnerability and the issue is fixed. Can you still reproduce the problem in the latest releases of ImageMagick? |
