ImageMagick image library: several flaws allow code execution and crashes

ImageMagick is a tool that many websites and programs use to process pictures. Attackers can abuse these flaws to take control of the service, crash it, or read data it should keep private.

How the attack works simplified

  1. 1Attacker sends imageCrafted file sent to the service
  2. 2ImageMagick processes itFlaw triggers during processing
  3. 3Memory is corruptedUnchecked data overwrites memory
  4. 4Code runsAttacker code runs with service rights
  5. ResultAttacker controls the server or service

What happened

Multiple vulnerabilities in ImageMagick enable arbitrary code execution with service privileges, memory corruption, cross-site scripting, denial of service, data manipulation and information disclosure; some are reachable remotely and anonymously, others only locally.

Why it is dangerous: A successful attack could let someone run their own code on a server that processes images, or take it offline, exposing data handled by that server. Web services and applications that process user-uploaded images are most at risk.

Are you affected?

You are affected if you run an ImageMagick version listed below on a server, application or workstation, especially one that processes images uploaded or supplied by users.

ImageMagick (versions not specified in the provided material)

What to do

  1. Identify every system and application that uses ImageMagick, including through third-party software
  2. Update ImageMagick to the latest version from the vendor or your operating system supplier
  3. Restrict or validate image uploads until the update is applied
  4. Check the official CERT-Bund (BSI) advisory for the exact affected and fixed versions
