CVE-2026-40915 · Severity: medium · CVSS 5.5 · Published 2026-04-15
A flaw was found in GIMP. A remote attacker could exploit an integer overflow vulnerability in the FITS image loader by providing a specially crafted FITS file. This integer overflow leads to a zero-byte memory allocation, which is then subjected to a heap buffer overflow when processing pixel data. Successful exploitation could result in a denial of service (DoS) or potentially arbitrary code execution.
