AI Insight

LLM-synthesized narrative grounded in this CVE's description and references.

ImageMagick versions prior to 7.0.9-0 have a division-by-zero flaw in MagickCore/gem-private.h that can cause application availability impact via crafted files.

Vulnerability

A flaw exists in ImageMagick's MagickCore/gem-private.h where processing a crafted file can trigger undefined behavior, specifically values outside the range of type unsigned char or a division by zero. This affects ImageMagick versions prior to 7.0.9-0 [1].

Exploitation

An attacker can submit a specially crafted file to an application that uses ImageMagick to process images. No authentication or special privileges are required; the file only needs to be processed by the vulnerable code path [1].

Impact

The undefined behavior most likely leads to an application crash, impacting availability. Red Hat Product Security rated this as Low severity because no specific impact beyond denial of service was demonstrated [1].

Mitigation

The issue is fixed in ImageMagick version 7.0.9-0. Users should upgrade to this version or later. For Red Hat Enterprise Linux 5, 6, and 7, this flaw is out of support scope. Inkscape on RHEL 8 is not affected as it no longer bundles ImageMagick [1].
