CVE-2026-6384: Gimp: gimp: arbitrary code execution or denial of service via buffer overflow in gif image processing

A flaw was found in gimp. This buffer overflow vulnerability in the GIF image loading component's `ReadJeffsImage` function allows an attacker to write beyond an allocated buffer by processing a specially crafted GIF file. This can lead to a denial of service or potentially arbitrary code execution.
