The remote CentOS Linux 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2020:5618 advisory.

  - Uninitialized Use in V8 in Google Chrome prior to 87.0.4280.88 allowed a remote attacker to obtain     potentially sensitive information from process memory via a crafted HTML page. (CVE-2020-16042)

  - Certain blit values provided by the user were not properly constrained leading to a heap buffer overflow     on some video drivers. This vulnerability affects Firefox < 84, Thunderbird < 78.6, and Firefox ESR <     78.6. (CVE-2020-26971)

  - Certain input to the CSS Sanitizer confused it, resulting in incorrect components being removed. This     could have been used as a sanitizer bypass. This vulnerability affects Firefox < 84, Thunderbird < 78.6,     and Firefox ESR < 78.6. (CVE-2020-26973)

  - When flex-basis was used on a table wrapper, a StyleGenericFlexBasis object could have been incorrectly     cast to the wrong type. This resulted in a heap user-after-free, memory corruption, and a potentially     exploitable crash. This vulnerability affects Firefox < 84, Thunderbird < 78.6, and Firefox ESR < 78.6.
    (CVE-2020-26974)

  - Using techniques that built on the slipstream research, a malicious webpage could have exposed both an     internal network's hosts as well as services running on the user's local machine. This vulnerability     affects Firefox < 84, Thunderbird < 78.6, and Firefox ESR < 78.6. (CVE-2020-26978)

  - When an extension with the proxy permission registered to receive <all_urls>, the proxy.onRequest callback     was not triggered for view-source URLs. While web content cannot navigate to such URLs, a user opening     View Source could have inadvertently leaked their IP address. This vulnerability affects Firefox < 84,     Thunderbird < 78.6, and Firefox ESR < 78.6. (CVE-2020-35111)

  - Mozilla developers reported memory safety bugs present in Firefox 83 and Firefox ESR 78.5. 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 < 84, Thunderbird < 78.6, and     Firefox ESR < 78.6. (CVE-2020-35113)

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