How to fix?

Upgrade Alpine:3.23 rust to version 1.91.1-r2 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream rust package and not the rust package as distributed by Alpine. See How to fix? for Alpine:3.23 relevant fixed versions and status.

Cargo incorrectly handled symlinks inside of crate tarballs downloaded from third-party registries, allowing a malicious crate to override the source code of another crate from the same registry. The severity of the vulnerability is medium for users of third-party registries. Users of crates.io are not affected, as crates.io forbids uploading crates containing any symlink.
