The remote CentOS Linux 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2020:5235 advisory.

  - Side-channel information leakage in graphics in Google Chrome prior to 87.0.4280.66 allowed a remote     attacker to leak cross-origin data via a crafted HTML page. (CVE-2020-16012)

  - A parsing and event loading mismatch in Firefox's SVG code could have allowed load events to fire, even     after sanitization. An attacker already capable of exploiting an XSS vulnerability in privileged internal     pages could have used this attack to bypass our built-in sanitizer. This vulnerability affects Firefox <     83, Firefox ESR < 78.5, and Thunderbird < 78.5. (CVE-2020-26951)

  - It was possible to cause the browser to enter fullscreen mode without displaying the security UI; thus     making it possible to attempt a phishing attack or otherwise confuse the user. This vulnerability affects     Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5. (CVE-2020-26953)

  - In some cases, removing HTML elements during sanitization would keep existing SVG event handlers and     therefore lead to XSS. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird <     78.5. (CVE-2020-26956)

  - Firefox did not block execution of scripts with incorrect MIME types when the response was intercepted and     cached through a ServiceWorker. This could lead to a cross-site script inclusion vulnerability, or a     Content Security Policy bypass. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and     Thunderbird < 78.5. (CVE-2020-26958)

  - During browser shutdown, reference decrementing could have occured on a previously freed object, resulting     in a use-after-free, memory corruption, and a potentially exploitable crash. This vulnerability affects     Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5. (CVE-2020-26959)

  - If the Compact() method was called on an nsTArray, the array could have been reallocated without updating     other pointers, leading to a potential use-after-free and exploitable crash. This vulnerability affects     Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5. (CVE-2020-26960)

  - When DNS over HTTPS is in use, it intentionally filters RFC1918 and related IP ranges from the responses     as these do not make sense coming from a DoH resolver. However when an IPv4 address was mapped through     IPv6, these addresses were erroneously let through, leading to a potential DNS Rebinding attack. This     vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5. (CVE-2020-26961)

  - Some websites have a feature Show Password where clicking a button will change a password field into a     textbook field, revealing the typed password. If, when using a software keyboard that remembers user     input, a user typed their password and used that feature, the type of the password field was changed,     resulting in a keyboard layout change and the possibility for the software keyboard to remember the typed     password. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5.
    (CVE-2020-26965)

  - Mozilla developers reported memory safety bugs present in Firefox 82 and Firefox ESR 78.4. Some of these     bugs showed evidence of memory corruption and we presume that with enough effort some of these could have     been exploited to run arbitrary code. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and     Thunderbird < 78.5. (CVE-2020-26968)

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