    "title": "Gimp: gimp: memory corruption due to integer overflow in ico file handling",
    "summary": "A flaw was found in GIMP. An integer overflow vulnerability exists when processing ICO image files, specifically in the `ico_read_info` and `ico_read_icon` functions. This issue arises because a size calculation for image buffers can wrap around due to a 32-bit integer evaluation, allowing oversized image headers to bypass security checks. A remote attacker could exploit this by providing a specially crafted ICO file, leading to a buffer overflow and memory corruption, which may result in an application level denial of service.",
