## Description

A denial of service vulnerability exists in self-hosted Next.js applications that have \`remotePatterns\` configured for the Image Optimizer. The image optimization endpoint (\`/\_next/image\`) loads external images entirely into memory without enforcing a maximum size limit, allowing an attacker to cause out-of-memory conditions by requesting optimization of arbitrarily large images. This vulnerability requires that \`remotePatterns\` is configured to allow image optimization from external domains and that the attacker can serve or control a large image on an allowed domain.  Strongly consider upgrading to 15.5.10 or 16.1.5 to reduce risk and prevent availability issues in Next applications.
