Vulnerability Title
Gimp: signed integer overflow in file-sgi (sgi-lib) causes the plugin to crash on rle sgi images
Source: CVE Program / CVE List V5
Vulnerability 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.
