"The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced
in the ALINUX3-SA-2022:0116 advisory.

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

    CVE-2019-12083:
    The Rust Programming Language Standard Library 1.34.x before 1.34.2 contains a stabilized method which, if
    overridden, can violate Rust's safety guarantees and cause memory unsafety. If the `Error::type_id` method
    is overridden then any type can be safely cast to any other type, causing memory safety vulnerabilities in
    safe code (e.g., out-of-bounds write or read). Code that does not manually implement Error::type_id is
    unaffected.

    CVE-2021-42574:
    ** DISPUTED ** An issue was discovered in the Bidirectional Algorithm in the Unicode Specification through
    14.0. It permits the visual reordering of characters via control sequences, which can be used to craft
    source code that renders different logic than the logical ordering of tokens ingested by compilers and
    interpreters. Adversaries can leverage this to encode source code for compilers accepting Unicode such
    that targeted vulnerabilities are introduced invisibly to human reviewers. NOTE: the Unicode Consortium
    offers the following alternative approach to presenting this concern. An issue is noted in the nature of
    international text that can affect applications that implement support for The Unicode Standard and the
    Unicode Bidirectional Algorithm (all versions). Due to text display behavior when text includes left-to-
    right and right-to-left characters, the visual order of tokens may be different from their logical order.
    Additionally, control characters needed to fully support the requirements of bidirectional text can
    further obfuscate the logical order of tokens. Unless mitigated, an adversary could craft source code such
    that the ordering of tokens perceived by human reviewers does not match what will be processed by a
    compiler/interpreter/etc. The Unicode Consortium has documented this class of vulnerability in its
    document, Unicode Technical Report #36, Unicode Security Considerations. The Unicode Consortium also
    provides guidance on mitigations for this class of issues in Unicode Technical Standard #39, Unicode
    Security Mechanisms, and in Unicode Standard Annex #31, Unicode Identifier and Pattern Syntax. Also, the
    BIDI specification allows applications to tailor the implementation in ways that can mitigate misleading
    visual reordering in program text; see HL4 in Unicode Standard Annex #9, Unicode Bidirectional Algorithm.

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

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