ZIP filename mismatch in Rust zip library through 9.0.4

The Rust zip library, through 9.0.4, treats Central Directory filenames as authoritative in ZipArchive while ZipStreamReader extracts using Local File Header names and does not reconcile the two. A crafted archive can look benign to a component that only checks the central directory, yet a streaming extractor writes an attacker-chosen path and content, potentially overwriting files a downstream service uses. Any application that stream-extracts untrusted ZIPs with this library is affected.
What to do: Upgrade the Rust zip library to 9.0.5.
| Product | Affected | Fixed in |

Description · NVD
zip is a zip library for Rust that supports reading and writing simple ZIP files. Through 9.0.4, ZipArchive treats Central Directory File Header filenames as authoritative while ZipStreamReader extracts using Local File Header filenames without reconciling the duplicate metadata in src/read/stream.rs. A crafted archive can therefore appear benign to a component that inspects the central directory but cause a streaming extractor to write a different attacker-selected path and content, potentially overwriting files used by a downstream service. This issue is fixed in version 9.0.5.
