Compensating controls
- Apply the linked authoritative mitigation while planning the permanent fix.
- Restrict local access and enforce least privilege on affected hosts.
- Monitor vendor guidance and exploitation sources for a material change.
Verification
- Confirm that the asset runs ImageMagick ImageMagick and falls inside the recorded affected range.
- Recheck the vendor advisory before scheduling a change because no verified fixed version is currently retained.
- Validate exposure, authentication requirements and compensating controls in the actual environment.
- Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Remediation availability differs by product scope
Verified remediation exists for at least one product or source, but 14 structured product or package states remain unresolved. Apply remediation only to the exact product branch confirmed by its source.

Distribution package intelligence
6 package statesRelease-specific package status
Alpine, Debian, ubuntu findings are scoped to the named distribution, release and source package. An absent finding does not mean a package is unaffected.
Repository candidate not checked
A published vendor fix does not prove that a matching update is enabled and installable on a particular asset. Confirm the local package candidate before scheduling remediation.

- Summary
- A flaw was found in ImageMagick. A user opening a specially crafted MIFF (Magick Image File Format) file in the display tool and right-clicking a tile to invoke the Load / Update menu item could trigger an overflow vulnerability. This overflow could lead to a denial of service, making the application unavailable.
- Remediation
- Users should avoid opening or interacting with untrusted MIFF (Magick Image File Format) files using the ImageMagick display tool. If the ImageMagick package is not essential for image display or other critical system functions, consider removing it. Be aware that removing ImageMagick may impact other applications that rely on its image processing capabilities.
Medium technical severity with no CISA KEV confirmation; remediate through the normal risk-based patch cycle unless local exposure raises the priority. Verified remediation exists for at least one product or source, but 14 structured product or package states remain unresolved. Apply remediation only to the exact product branch confirmed by its source.
Fix availability varies by product01
What, why and how
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to 7.1.2-21 and 6.9.13-46, a malicious MIFF file could trigger an overflow when a user opens it in the display tool and right-clicks a tile to invoke the Load / Update menu item. This vulnerability is fixed in 7.1.2-21 and 6.9.13-46.

Prior to 7.1.2-21 and 6.9.13-46, a malicious MIFF file could trigger an overflow when a user opens it in the display tool and right-clicks a tile to invoke the Load / Update menu item. This vulnerability is fixed in 7.1.2-21 and 6.9.13-46.
Why
A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).
How
An attacker operating through local access may attempt exploitation without authentication after a user interaction. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

Exploit reality and attack path
CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.
Observed exploitation No confirmed evidence
?
Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.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 None recorded
?
Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.
- Likely attack path
- local access → Stack-based Buffer Overflow → cause the confidentiality, integrity or availability impact described by the vendor
- Attack surface
- Local
- Privileges required
- None: unauthenticated exploitation is possible
- User interaction
- Required interaction required
- Attack complexity
- Low: no specialised conditions are recorded
- Security boundary
- Unchanged: impact remains within the vulnerable component's security authority
- Weakness
?
CWE means Common Weakness Enumeration: a standard category for the underlying weakness. - CWE-121 ↗
CWE-121: Stack-based Buffer Overflow. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).

- The issue can support a local privilege or sandbox boundary transition; normal system utilities may then be available in the gained context.

- Action
- Use the product-specific evidence above. Patch only products with a verified fixed release, and keep every affected or under-investigation state without a matching fix in the remediation queue.
- Workaround
- Users should avoid opening or interacting with untrusted MIFF (Magick Image File Format) files using the ImageMagick display tool. If the ImageMagick package is not essential for image display or other critical system functions, consider removing it. Be aware that removing ImageMagick may impact other applications that rely on its image processing capabilities.
