What is CVE-2026-40915?

A flaw was discovered in GIMP's handling of FITS files, where an integer overflow can occur in the FITS image loader. An attacker could potentially exploit this vulnerability by submitting a specially crafted FITS file. This exploitation leads to a zero-byte memory allocation that may cause a heap buffer overflow during pixel data processing. As a consequence, this could enable a remote attacker to trigger a denial of service or execute arbitrary code on the affected system.
