DescriptionCVE.org

A flaw was found in the Seattle FilmWorks plugin in GIMP. When processing a specially crafted SFW image file, the plugin allocates a Variable-Length Array (VLA) on the stack without integer overflow checks, causing an unbounded stack allocation. This issue leads to an application crash, resulting in a denial of service.

Hypothetical attack flow derived from CVE metadata

Access
Deliver crafted SFW image to target user
Delivery
User opens file in GIMP
Exploit
SFW plugin parses malformed image header
Execution
Integer overflow produces unbounded VLA dimension
Impact
Stack exhaustion crashes GIMP process

Vulnerability AssessmentAI

Exploitation Exploitation requires that the target user actively open a specially crafted SFW image file in GIMP - user interaction is mandatory per the CVSS UI:R metric. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment Real-world risk is moderate-to-low. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker crafts a malicious SFW image file with a header value engineered to cause integer overflow during VLA size calculation in the GIMP Seattle FilmWorks plugin. The file is delivered to a target user via email attachment, file share, or a download link. …
Remediation No vendor-released patch with a confirmed fixed version has been identified at time of analysis. … Detailed patch versions, workarounds, and compensating controls in full report.
