CVE-2026-66757 (GCVE-0-2026-66757)

Vulnerability from cvelistv5 – Published: 2026-07-27 19:07 – Updated: 2026-07-27 20:21

Title

Gimp: signed integer overflow in file-sgi (sgi-lib) causes the plugin to crash on rle sgi images

Summary

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.

Severity
