The remote CentOS Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2021:4033 advisory.

  - 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.
    (CVE-2021-42574)

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