"The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied
patch available.

  - Starting from Rust 1.87.0 and before Rust 1.89.0, the tier 3 Cygwin target (`x86_64-pc-cygwin`) didn't
    correctly handle path separators, causing the standard library's Path API to ignore path components
    separated by backslashes. Due to this, programs compiled for Cygwin that validate paths could misbehave,
    potentially allowing path traversal attacks or malicious filesystem operations. Rust 1.89.0 fixes the
    issue by handling both Win32 and Unix style paths in the standard library for the Cygwin target. While we
    assess the severity of this vulnerability as medium, please note that the tier 3 Cygwin compilation
    target is only available when building it from source: no pre-built binaries are distributed by the Rust
    project, and it cannot be installed through Rustup. Unless you manually compiled the `x86_64-pc-cygwin`
    target you are not affected by this vulnerability. Users of the tier 1 MinGW target (`x86_64-pc-windows-
    gnu`) are also explicitly not affected. (CVE-2025-11233)

Note that Nessus relies on the presence of the package as reported by the vendor.");
