The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has firefox packages installed that are affected by multiple vulnerabilities:

  - When a master password is set, it is required to be     entered again before stored passwords can be accessed in     the 'Saved Logins' dialog. It was found that locally     stored passwords can be copied to the clipboard thorough     the 'copy password' context menu item without re-     entering the master password if the master password had     been previously entered in the same session, allowing     for potential theft of stored passwords. This     vulnerability affects Firefox < 68.0.2 and Firefox ESR <     68.0.2. (CVE-2019-11733)

  - Mozilla developers and community members reported memory     safety bugs present in Firefox 68, Firefox ESR 68, and     Firefox 60.8. 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 Firefox < 69,     Thunderbird < 68.1, Thunderbird < 60.9, Firefox ESR <     60.9, and Firefox ESR < 68.1. (CVE-2019-11740)

  - A same-origin policy violation occurs allowing the theft     of cross-origin images through a combination of SVG     filters and a <canvas> element due to an error in     how same-origin policy is applied to cached image     content. The resulting same-origin policy violation     could allow for data theft. This vulnerability affects     Firefox < 69, Thunderbird < 68.1, Thunderbird < 60.9,     Firefox ESR < 60.9, and Firefox ESR < 68.1.
    (CVE-2019-11742)

  - Navigation events were not fully adhering to the W3C's     Navigation-Timing Level 2 draft specification in some     instances for the unload event, which restricts access     to detailed timing attributes to only be same-origin.
    This resulted in potential cross-origin information     exposure of history through timing side-channel attacks.
    This vulnerability affects Firefox < 69, Thunderbird <     68.1, Thunderbird < 60.9, Firefox ESR < 60.9, and     Firefox ESR < 68.1. (CVE-2019-11743)

  - Some HTML elements, such as <title> and     <textarea>, can contain literal angle brackets     without treating them as markup. It is possible to pass     a literal closing tag to .innerHTML on these elements,     and subsequent content after that will be parsed as if     it were outside the tag. This can lead to XSS if a site     does not filter user input as strictly for these     elements as it does for other elements. This     vulnerability affects Firefox < 69, Thunderbird < 68.1,     Thunderbird < 60.9, Firefox ESR < 60.9, and Firefox ESR     < 68.1. (CVE-2019-11744)

  - A use-after-free vulnerability can occur while     manipulating video elements if the body is freed while     still in use. This results in a potentially exploitable     crash. This vulnerability affects Firefox < 69,     Thunderbird < 68.1, Thunderbird < 60.9, Firefox ESR <     60.9, and Firefox ESR < 68.1. (CVE-2019-11746)

  - It is possible to delete an IndexedDB key value and     subsequently try to extract it during conversion. This     results in a use-after-free and a potentially     exploitable crash. This vulnerability affects Firefox <     69, Thunderbird < 68.1, Thunderbird < 60.9, Firefox ESR     < 60.9, and Firefox ESR < 68.1. (CVE-2019-11752)

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

The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4150-1 advisory.

  - Encrypted S/MIME parts in a crafted multipart/alternative message can leak plaintext when included in a a     HTML reply/forward. This vulnerability affects Thunderbird < 68.1 and Thunderbird < 60.9. (CVE-2019-11739)

  - Mozilla developers and community members reported memory safety bugs present in Firefox 68, Firefox ESR     68, and Firefox 60.8. 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     Firefox < 69, Thunderbird < 68.1, Thunderbird < 60.9, Firefox ESR < 60.9, and Firefox ESR < 68.1.

  - Navigation events were not fully adhering to the W3C's Navigation-Timing Level 2 draft specification in     some instances for the unload event, which restricts access to detailed timing attributes to only be same-     origin.

Multiple security issues were discovered in Firefox. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to obtain sensitive information, bypass Content Security Policy (CSP) protections, bypass same-origin restrictions, conduct cross-site scripting (XSS) attacks, cause a denial of service, or execute arbitrary code. (CVE-2019-5849, CVE-2019-11734, CVE-2019-11735, CVE-2019-11737, CVE-2019-11738, CVE-2019-11740, CVE-2019-11742, CVE-2019-11743, CVE-2019-11744, CVE-2019-11746, CVE-2019-11748, CVE-2019-11749, CVE-2019-11750, CVE-2019-11752)

It was discovered that a compromised content process could log in to a malicious Firefox Sync account. An attacker could potentially exploit this, in combination with another vulnerability, to disable the sandbox. (CVE-2019-9812)

It was discovered that addons.mozilla.org and accounts.firefox.com could be loaded in to the same content process. An attacker could potentially exploit this, in combination with another vulnerability that allowed a cross-site scripting (XSS) attack, to modify browser settings. (CVE-2019-11741)

It was discovered that the 'Forget about this site' feature in the history pane removes HTTP Strict Transport Security (HSTS) settings for sites on the pre-load list. An attacker could potentially exploit this to bypass the protections offered by HSTS. (CVE-2019-11747).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
