Lifecycle Timeline
2DescriptionCVE.org
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. User interaction is required to open the malicious file.
Technical ContextAI
The vulnerability resides in the file-icns plugin's icns_decompress function, which processes ICNS (Apple Icon Image) files. During mask decompression, the plugin fails to validate a cursor against the allocated buffer size before reading data. This classic CWE-125 out-of-bounds read occurs on the heap, resulting in exposure of adjacent memory. CPE data is not provided, but the affected component is GIMP with the ICNS plugin enabled. No specific version range is confirmed, though Red Hat's advisory suggests the flaw exists in GIMP as shipped in their distributions.
RemediationAI
No vendor-released patch is confirmed from the provided references. The upstream GitLab issue likely contains a fix, but no specific version number is available. As a workaround, disable or remove the file-icns plugin to prevent exploitation, though this will break support for ICNS icons. Alternatively, users should avoid opening ICNS files from untrusted sources. Monitor the GIMP security announcements and Red Hat advisory for official updates.
