Short explanation

ImageMagick contains a null pointer dereference in the DJVU decoder due to unchecked memory allocation results. Attackers can supply a crafted DJVU image to cause process crashes and denial of service.

Why does it matter?

This vulnerability allows attackers to cause a denial of service in target processes via maliciously supplied image files. Sources exhibit conflicting severity and CVSS base score evaluations.

What should be done?

  • Follow vendor security advisories
  • Update affected ImageMagick versions

Show the technical text from the sources

ImageMagick before 6.9.13-58 and 7.x before 7.1.2-33 contains a null pointer dereference in the DJVU decoder because the result of a memory allocation is not checked before use. Attackers can supply a DJVU image that, when processed under conditions where the allocation fails, crashes the process and causes a denial of service.
