Hi,

The following vulnerability was published for gimp.

CVE-2026-59087[0]:
| A flaw was found in the GIMP image manipulation program,
| specifically within its Seattle Filmworks file loader. A remote
| attacker could exploit this vulnerability by tricking a user into
| opening a specially crafted Seattle Filmworks file. This could lead
| to a heap overflow, allowing the attacker to write several kilobytes
| of controlled data beyond the intended memory buffer. Such an
| overflow can result in memory corruption, potentially leading to
| arbitrary code execution or a denial of service.
