The remote CentOS Linux 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2020:0576 advisory.

  - When deriving an identifier for an email message, uninitialized memory was used in addition to the message     contents. This vulnerability affects Thunderbird < 68.5. (CVE-2020-6792)

  - When processing an email message with an ill-formed envelope, Thunderbird could read data from a random     memory location. This vulnerability affects Thunderbird < 68.5. (CVE-2020-6793)

  - If a user saved passwords before Thunderbird 60 and then later set a master password, an unencrypted copy     of these passwords is still accessible. This is because the older stored password file was not deleted     when the data was copied to a new format starting in Thunderbird 60. The new master password is added only     on the new file. This could allow the exposure of stored password data outside of user expectations. This     vulnerability affects Thunderbird < 68.5. (CVE-2020-6794)

  - When processing a message that contains multiple S/MIME signatures, a bug in the MIME processing code     caused a null pointer dereference, leading to an unexploitable crash. This vulnerability affects     Thunderbird < 68.5. (CVE-2020-6795)

  - If a template tag was used in a select tag, the parser could be confused and allow JavaScript parsing and     execution when it should not be allowed. A site that relied on the browser behaving correctly could suffer     a cross-site scripting vulnerability as a result. In general, this flaw cannot be exploited through email     in the Thunderbird product because scripting is disabled when reading mail, but is potentially a risk in     browser or browser-like contexts. This vulnerability affects Thunderbird < 68.5, Firefox < 73, and Firefox     < ESR68.5. (CVE-2020-6798)

  - Mozilla developers and community members reported memory safety bugs present in Firefox 72 and Firefox ESR     68.4. 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. In general, these flaws cannot be exploited     through email in the Thunderbird product because scripting is disabled when reading mail, but are     potentially risks in browser or browser-like contexts. This vulnerability affects Thunderbird < 68.5,     Firefox < 73, and Firefox < ESR68.5. (CVE-2020-6800)

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