  "title": "Memory exhaustion in rust zip legacy ZIP decoders",
  "summary": "Rust applications using the `zip` crate with the `legacy-zip` feature enabled are affected when they process attacker-controlled ZIP archives containing legacy-compressed entries. A crafted Shrink, Reduce, or Implode entry can force full in-memory decompression despite caller read limits, potentially causing denial of service.",
