A flaw was found in the file-icns plugin in GIMP. When applying a decompressed mask during ICNS image processing, the plugin reads from the mask data buffer without verifying if the cursor exceeds the allocated resource size. If a crafted file contains a truncated mask resource, the icns_decompress function continues reading past the bounds of the buffer. This out-of-bounds read vulnerability results in information disclosure of heap contents, where memory contents are leaked as alpha channel pixel values, or a crash leading to a denial of service if unmapped memory is accessed.
AnalysisAI
Information disclosure and denial of service in GIMP's file-icns plugin allow local attackers to leak heap memory contents via a crafted ICNS image file. When processing a truncated mask resource, the plugin performs an out-of-bounds read, leaking heap data as alpha channel pixel values or crashing the application. …

Vulnerability AssessmentAI
| Exploitation | User must open a specially crafted ICNS image file with a truncated mask resource in GIMP while the file-icns plugin is active. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS base score 7.1 (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:H) indicates a local attack with no privileges and mandatory user interaction. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker sends a crafted ICNS file containing a truncated mask resource to a victim, perhaps via email or malicious website. The victim opens the file in GIMP, triggering the out-of-bounds read. … |
| Remediation | No vendor-released patch is confirmed from the provided references. … Detailed patch versions, workarounds, and compensating controls in full report. |
