CVE-2026-40915
A remote attacker could exploit an integer overflow vulnerability in the FITS image loader by providing a specially crafted FITS file.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.38%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
