The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:1172 advisory.
qt5-qtbase: Double free in QXmlStreamReader (CVE-2018-15518)
qt5-qtsvg: Invalid parsing of malformed url reference resulting in a denial of service (CVE-2018-19869)
qt5-qtbase: QImage allocation failure in qgifhandler (CVE-2018-19870)
qt5-qtimageformats: QTgaFile CPU exhaustion (CVE-2018-19871)
qt: Malformed PPM image causing division by zero and crash in qppmhandler.cpp (CVE-2018-19872)
qt5-qtbase: QBmpHandler segmentation fault on malformed BMP file (CVE-2018-19873)
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
