"The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is,
therefore, affected by multiple vulnerabilities as referenced in the TSSA-2024:0635 advisory.

    Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

    CVE-2023-38497:
    Cargo downloads the Rust projects dependencies and compiles the project. Cargo prior to version 0.72.2,
    bundled with Rust prior to version 1.71.1, did not respect the umask when extracting crate archives on
    UNIX-like systems. If the user downloaded a crate containing files writeable by any local user, another
    local user could exploit this to change the source code compiled and executed by the current user. To
    prevent existing cached extractions from being exploitable, the Cargo binary version 0.72.2 included in
    Rust 1.71.1 or later will purge caches generated by older Cargo versions automatically. As a workaround,
    configure one's system to prevent other local users from accessing the Cargo directory, usually located in
    `~/.cargo`.

    CVE-2023-40030:
    Cargo downloads a Rust projects dependencies and compiles the project. Starting in Rust 1.60.0 and
    prior to 1.72, Cargo did not escape Cargo feature names when including them in the report generated by
    `cargo build --timings`. A malicious package included as a dependency may inject nearly arbitrary HTML
    here, potentially leading to cross-site scripting if the report is subsequently uploaded somewhere. The
    vulnerability affects users relying on dependencies from git, local paths, or alternative registries.
    Users who solely depend on crates.io are unaffected.

    Rust 1.60.0 introduced `cargo build --timings`, which produces a report of how long the different steps of
    the build process took. It includes lists of Cargo features for each crate. Prior to Rust 1.72, Cargo
    feature names were allowed to contain almost any characters (with some exceptions as used by the feature
    syntax), but it would produce a future incompatibility warning about them since Rust 1.49. crates.io is
    far more stringent about what it considers a valid feature name and has not allowed such feature names. As
    the feature names were included unescaped in the timings report, they could be used to inject Javascript
    into the page, for example with a feature name like `features = [<img src='' onerror=alert(0)]`. If this
    report were subsequently uploaded to a domain that uses credentials, the injected Javascript could access
    resources from the website visitor.

    This issue was fixed in Rust 1.72 by turning the future incompatibility warning into an error. Users
    should still exercise care in which package they download, by only including trusted dependencies in their
    projects. Please note that even with these vulnerabilities fixed, by design Cargo allows arbitrary code
    execution at build time thanks to build scripts and procedural macros: a malicious dependency will be able
    to cause damage regardless of these vulnerabilities. crates.io has server-side checks preventing this
    attack, and there are no packages on crates.io exploiting these vulnerabilities. crates.io users still
    need to excercise care in choosing their dependencies though, as remote code execution is allowed by
    design there as well.
