  "title": "Denial of service in Rust zip legacy ZIP extraction",
  "summary": "Rust applications using the `zip` crate with the `legacy-zip` feature enabled are affected when they extract attacker-controlled ZIP archives through `ZipArchive::extract()`. A crafted archive can trigger an unhandled panic and terminate the archive-processing process. Exploitation requires an application to enable legacy ZIP codecs and process untrusted archives with the affected extraction API.",
  "mitigation": "Upgrade the Rust `zip` crate to version 9.0.0 or later. Until upgraded, disable the `legacy-zip` feature and avoid extracting untrusted archives through the affected API.",
