High [CVE-2026-66759] out-of-bounds read in file-icns plugin causes information disclosure or crash on crafted ICNS images
CVE-2026-66759Source published Source updated
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. To exploit this vulnerability, an attacker needs to convince a user to process a specially crafted ICNS image with GIMP, reducing the likelihood of exploitation. Due to this reason, this flaw has been rated with…
