Summary: A flaw was found in ImageMagick, a widely used image editing and manipulation software. This vulnerability arises from a NULL pointer dereference that occurs when the software attempts to create temporary files and fails. An attacker could exploit this issue to trigger an application crash, leading to a Denial of Service (DoS).
Remediation: To reduce the risk associated with this vulnerability, avoid processing untrusted SFW image files with ImageMagick. If ImageMagick is deployed in environments where it processes untrusted input, consider implementing sandboxing or resource limits for ImageMagick processes to contain potential crashes and limit impact.

What, why and how

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-15 and 6.9.13-40, in `ReadSFWImage()` (`coders/sfw.c`), when temporary file creation fails, `read_info` is destroyed before its `filename` member is accessed, causing a NULL pointer dereference and crash. Versions 7.1.2-15 and 6.9.13-40 contain a patch.

What

Why

The product dereferences a pointer that it expects to be valid but is NULL.

How

An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may disrupt the affected service.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation

Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.

No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material

Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.

None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.
