"The remote Alibaba Cloud Linux 3 host has packages installed that are affected by a vulnerability as referenced in the
ALINUX3-SA-2022:0217 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2022-21658:
    Rust is a multi-paradigm, general-purpose programming language designed for performance and safety,
    especially safe concurrency. The Rust Security Response WG was notified that the `std::fs::remove_dir_all`
    standard library function is vulnerable a race condition enabling symlink following (CWE-363). An attacker
    could use this security issue to trick a privileged program into deleting files and directories the
    attacker couldn't otherwise access or delete. Rust 1.0.0 through Rust 1.58.0 is affected by this
    vulnerability with 1.58.1 containing a patch. Note that the following build targets don't have usable APIs
    to properly mitigate the attack, and are thus still vulnerable even with a patched toolchain: macOS before
    version 10.10 (Yosemite) and REDOX. We recommend everyone to update to Rust 1.58.1 as soon as possible,
    especially people developing programs expected to run in privileged contexts (including system daemons and
    setuid binaries), as those have the highest risk of being affected by this. Note that adding checks in
    your codebase before calling remove_dir_all will not mitigate the vulnerability, as they would also be
    vulnerable to race conditions like remove_dir_all itself. The existing mitigation is working as intended
    outside of race conditions.

Tenable has extracted the preceding description block directly from the Alibaba Cloud Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
