The file-sgi plugin in GIMP is vulnerable to an integer overflow when processing RLE-compressed SGI images, which can lead to a denial of service due to undefined behavior. Specifically, if an attacker crafts an image with maximum header dimensions, it triggers a memory allocation failure that crashes the plugin. Users and administrators of GIMP should prioritize this vulnerability to mitigate potential disruptions in service.

Original NVD Description

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.
