medium Nessus Plugin ID 316871
Language:
Synopsis
The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.Description
The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.- 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. (CVE-2026-5223)
Note that Nessus relies on the presence of the package as reported by the vendor.
