description

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.

fixed in 9.0.0
