"The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the
RLSA-2020:4690 advisory.

  - Qt through 5.14 allows an exponential XML entity expansion attack via a crafted SVG document that is
    mishandled in QXmlStreamReader, a related issue to CVE-2003-1564. (CVE-2015-9541)

  - In Qt through 5.14.1, the WebSocket implementation accepts up to 2GB for frames and 2GB for messages.
    Smaller limits cannot be configured. This makes it easier for attackers to cause a denial of service
    (memory consumption). (CVE-2018-21035)

  - Out of bounds write in Intel(R) PROSet/Wireless WiFi products on Windows 10 may allow an authenticated
    user to potentially enable denial of service via local access. (CVE-2020-0569)

  - Uncontrolled search path in the QT Library before 5.14.0, 5.12.7 and 5.9.10 may allow an authenticated
    user to potentially enable elevation of privilege via local access. (CVE-2020-0570)

  - Qt 5.12.2 through 5.14.2, as used in unofficial builds of Mumble 1.3.0 and other products, mishandles
    OpenSSL's error queue, which can cause a denial of service to QSslSocket users. Because errors leak in
    unrelated TLS sessions, an unrelated session may be disconnected when any handshake fails. (Mumble 1.3.1
    is not affected, regardless of the Qt version.) (CVE-2020-13962)

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