AnalysisAIv1 – Jul 27, 2026

An integer overflow in GIMP's file-sgi plugin, triggered by a crafted RLE-compressed SGI image, causes denial of service by crashing the plugin. The vulnerability affects GIMP versions with the file-sgi plugin and requires a user to open a malicious image file. No public exploit or active exploitation is known at this time; the issue is being tracked by GNOME and Red Hat.

DescriptionCVE.org

A flaw was found in the file-sgi plugin in GIMP. When processing an RLE-compressed SGI image, the plugin allocates memory for a row table. The image header dimensions (ysize and zsize) are read as 16-bit unsigned integers. If a crafted file sets both dimensions to their maximum value (65535), the multiplication ysize * zsize overflows the standard 32-bit int boundary before being passed to calloc. This integer overflow issue results in undefined behavior, aborting the plugin and causing a denial of service.

Attack Technique

Integer Overflow MEDIUM

Integer overflow occurs when an arithmetic operation produces a result that exceeds the maximum value a given integer type can store.

Denial of Service MEDIUM

Denial of Service attacks render applications or systems unavailable by overwhelming resources or triggering failure conditions.
