CVE-2026-61871

ImageMagick before 7.1.2-26 Memory Leak in ICON decoder

Published Jul 15, 2026 CVSS 4.0 · 6.3 Medium EPSS < 1% KEV · Not listed

Description

ImageMagick before 7.1.2-26 and 6.9.13-51 contains a memory leak in the ICON decoder that occurs when a memory allocation fails. Processing a crafted ICON file that triggers an allocation failure leaks memory, which may lead to a denial of service.

Analysis

Technical impact

ImageMagick versions prior to 7.1.2-26 and 6.9.13-51 contain a flaw in the ICON decoder that triggers a memory leak when a memory allocation fails. If a crafted Icon file is processed, repeated allocation failures leak memory, potentially exhausting system resources and rendering the processing tool or any application that uses the library unavailable. The underlying weakness is an uncontrolled memory allocation (CWE-401) and improper handling of an allocation failure (CWE-772).

Affected Systems

The vulnerability affects installations of the ImageMagick image processing suite that are older than version 7.1.2-26 or 6.9.13-51. All users of pre‑release releases before these updates are potentially impacted.

Risk and Exploitability

The CVSS base score of 6.3 indicates moderate severity, while an EPSS score of less than 1% shows a very low predicted exploitation probability. The issue is not listed in the CISA KEV catalog. Exploitation requires an attacker to supply a crafted Icon file to the ImageMagick library, either by invoking the command‑line tools directly or by embedding the file in an application that calls the library. Because this is a memory‑leak flaw rather than a code‑execution flaw, the primary impact is on system or application availability rather than confidentiality or integrity.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

Upgrade ImageMagick to version 7.1.2-26 or newer, or to 6.9.13-51 or newer if that version bundle includes the fix.
If an upgrade is not immediately possible, configure the application or environment to reject or isolate processing of Icon files, limiting the exposure of the memory‑leak surface.
Implement memory‑usage monitoring for processes that invoke ImageMagick to detect or mitigate exhaustion caused by repeated allocation failures.
