The version of Mozilla Thunderbird installed on the remote OSX host is prior to 60.0. It is, therefore, affected by multiple vulnerabilities.

The remote NewStart CGSL host, running version MAIN 4.05, has thunderbird packages installed that are affected by multiple vulnerabilities:

  - Decrypted S/MIME parts, when included in HTML crafted     for an attack, can leak plaintext when included in a a     HTML reply/forward. This vulnerability affects     Thunderbird < 52.9. (CVE-2018-12372)

  - Plaintext of decrypted emails can leak through by user     submitting an embedded form by pressing enter key within     a text input field. This vulnerability affects     Thunderbird < 52.9. (CVE-2018-12374)

  - A buffer overflow can occur when rendering canvas     content while adjusting the height and width of the     canvas element dynamically, causing data to be written     outside of the currently computed boundaries. This     results in a potentially exploitable crash. This     vulnerability affects Thunderbird < 60, Thunderbird <     52.9, Firefox ESR < 60.1, Firefox ESR < 52.9, and     Firefox < 61. (CVE-2018-12359)

  - A use-after-free vulnerability can occur when deleting     an input element during a mutation event handler     triggered by focusing that element. This results in a     potentially exploitable crash. This vulnerability     affects Thunderbird < 60, Thunderbird < 52.9, Firefox     ESR < 60.1, Firefox ESR < 52.9, and Firefox < 61.
    (CVE-2018-12360)

  - An integer overflow can occur during graphics operations     done by the Supplemental Streaming SIMD Extensions 3     (SSSE3) scaler, resulting in a potentially exploitable     crash. This vulnerability affects Thunderbird < 60,     Thunderbird < 52.9, Firefox ESR < 60.1, Firefox ESR <     52.9, and Firefox < 61. (CVE-2018-12362)

  - A use-after-free vulnerability can occur when script     uses mutation events to move DOM nodes between     documents, resulting in the old document that held the     node being freed but the node still having a pointer     referencing it. This results in a potentially     exploitable crash. This vulnerability affects     Thunderbird < 60, Thunderbird < 52.9, Firefox ESR <     60.1, Firefox ESR < 52.9, and Firefox < 61.
    (CVE-2018-12363)

  - NPAPI plugins, such as Adobe Flash, can send non-simple     cross-origin requests, bypassing CORS by making a same-     origin POST that does a 307 redirect to the target site.
    This allows for a malicious site to engage in cross-site     request forgery (CSRF) attacks. This vulnerability     affects Thunderbird < 60, Thunderbird < 52.9, Firefox     ESR < 60.1, Firefox ESR < 52.9, and Firefox < 61.
    (CVE-2018-12364)

  - A compromised IPC child process can escape the content     sandbox and list the names of arbitrary files on the     file system without user consent or interaction. This     could result in exposure of private local files. This     vulnerability affects Thunderbird < 60, Thunderbird <     52.9, Firefox ESR < 60.1, Firefox ESR < 52.9, and     Firefox < 61. (CVE-2018-12365)

  - An invalid grid size during QCMS (color profile)     transformations can result in the out-of-bounds read     interpreted as a float value. This could leak private     data into the output. This vulnerability affects     Thunderbird < 60, Thunderbird < 52.9, Firefox ESR <     60.1, Firefox ESR < 52.9, and Firefox < 61.
    (CVE-2018-12366)

  - Memory safety bugs present in Firefox 60, Firefox ESR     60, and Firefox ESR 52.8. Some of these bugs showed     evidence of memory corruption and we presume that with     enough effort that some of these could be exploited to     run arbitrary code. This vulnerability affects     Thunderbird < 60, Thunderbird < 52.9, Firefox ESR <     60.1, Firefox ESR < 52.9, and Firefox < 61.
    (CVE-2018-5188)

  - dDecrypted S/MIME parts hidden with CSS or the plaintext     HTML tag can leak plaintext when included in a HTML     reply/forward. This vulnerability affects Thunderbird <     52.9. (CVE-2018-12373)

  - Memory safety bugs present in Firefox 61 and Firefox ESR     60.1. Some of these bugs showed evidence of memory     corruption and we presume that with enough effort that     some of these could be exploited to run arbitrary code.
    This vulnerability affects Firefox < 62, Firefox ESR <     60.2, and Thunderbird < 60.2.1. (CVE-2018-12376)

  - A use-after-free vulnerability can occur when refresh     driver timers are refreshed in some circumstances during     shutdown when the timer is deleted while still in use.
    This results in a potentially exploitable crash. This     vulnerability affects Firefox < 62, Firefox ESR < 60.2,     and Thunderbird < 60.2.1. (CVE-2018-12377)

  - A use-after-free vulnerability can occur when an     IndexedDB index is deleted while still in use by     JavaScript code that is providing payload values to be     stored. This results in a potentially exploitable crash.
    This vulnerability affects Firefox < 62, Firefox ESR <     60.2, and Thunderbird < 60.2.1. (CVE-2018-12378)

  - When the Mozilla Updater opens a MAR format file which     contains a very long item filename, an out-of-bounds     write can be triggered, leading to a potentially     exploitable crash. This requires running the Mozilla     Updater manually on the local system with the malicious     MAR file in order to occur. This vulnerability affects     Firefox < 62, Firefox ESR < 60.2, and Thunderbird <     60.2.1. (CVE-2018-12379)

  - If a user saved passwords before Firefox 58 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 Firefox 58. 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 Firefox     < 62, Firefox ESR < 60.2.1, and Thunderbird < 60.2.1.
    (CVE-2018-12383)

  - Firefox proxy settings can be bypassed by using the     automount feature with autofs to create a mount point on     the local file system. Content can be loaded from this     mounted file system directly using a `file:` URI,     bypassing configured proxy settings. This issue only     affects OS X in default configuration; on Linux systems,     autofs must also be installed for the vulnerability to     occur. (CVE-2017-16541)

  - Mozilla developers and community members reported memory     safety bugs present in Firefox ESR 60.2. Some of these     bugs showed evidence of memory corruption and we presume     that with enough effort that some of these could be     exploited to run arbitrary code. This vulnerability     affects Firefox ESR < 60.3 and Thunderbird < 60.3.
    (CVE-2018-12389)

  - When manipulating user events in nested loops while     opening a document through script, it is possible to     trigger a potentially exploitable crash due to poor     event handling. This vulnerability affects Firefox < 63,     Firefox ESR < 60.3, and Thunderbird < 60.3.
    (CVE-2018-12392)

  - A potentially exploitable crash in TransportSecurityInfo     used for SSL can be triggered by data stored in the     local cache in the user profile directory. This issue is     only exploitable in combination with another     vulnerability allowing an attacker to write data into     the local cache or from locally installed malware. This     issue also triggers a non-exploitable startup crash for     users switching between the Nightly and Release versions     of Firefox if the same profile is used. This     vulnerability affects Thunderbird < 60.2.1, Firefox ESR     < 60.2.1, and Firefox < 62.0.2. (CVE-2018-12385)

  - Mozilla developers and community members reported memory     safety bugs present in Firefox 62 and Firefox ESR 60.2.
    Some of these bugs showed evidence of memory corruption     and we presume that with enough effort that some of     these could be exploited to run arbitrary code. This     vulnerability affects Firefox < 63, Firefox ESR < 60.3,     and Thunderbird < 60.3. (CVE-2018-12390)

  - A potential vulnerability was found in 32-bit builds     where an integer overflow during the conversion of     scripts to an internal UTF-16 representation could     result in allocating a buffer too small for the     conversion. This leads to a possible out-of-bounds     write. *Note: 64-bit builds are not vulnerable to this     issue.*. This vulnerability affects Firefox < 63,     Firefox ESR < 60.3, and Thunderbird < 60.3.
    (CVE-2018-12393)

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

Versions of Mozilla Firefox ESR earlier than 60.1 are unpatched for the following vulnerabilities :
