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 CentOS Linux 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the CESA-2019:2663 advisory.

  - Mozilla: Cross-origin access to unload event attributes (CVE-2019-11743)

  - Mozilla: XSS by breaking out of title and textarea elements using innerHTML (CVE-2019-11744)

  - Mozilla: Use-after-free while manipulating video (CVE-2019-11746)

  - Mozilla: 'Forget about this site' removes sites from pre-loaded HSTS list (CVE-2019-11747)

  - Mozilla: Persistence of WebRTC permissions in a third party context (CVE-2019-11748)

  - Mozilla: Camera information available without prompting using getUserMedia (CVE-2019-11749)

  - Mozilla: Type confusion in Spidermonkey (CVE-2019-11750)

  - Mozilla: Use-after-free while extracting a key value in IndexedDB (CVE-2019-11752)

  - Mozilla: Sandbox escape through Firefox Sync (CVE-2019-9812)

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

    There is no known workaround at this time.

The remote SUSE Linux SLES11 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2019:14173-1 advisory.

  - 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)

  - The Firefox installer allows Firefox to be installed to a custom user writable location, leaving it     unprotected from manipulation by unprivileged users or malware. If the Mozilla Maintenance Service is     manipulated to update this unprotected location and the updated maintenance service in the unprotected     location has been altered, the altered maintenance service can run with elevated privileges during the     update process due to a lack of integrity checks. This allows for privilege escalation if the executable     has been replaced locally. *Note: This attack requires local system access and only affects Windows.
    Other operating systems are not affected.*. This vulnerability affects Firefox < 69, Firefox ESR < 60.9,     and Firefox ESR < 68.1. (CVE-2019-11753)

  - Given a compromised sandboxed content process due to a separate vulnerability, it is possible to escape     that sandbox by loading accounts.firefox.com in that process and forcing a log-in to a malicious Firefox     Sync account. Preference settings that disable the sandbox are then synchronized to the local machine and     the compromised browser would restart without the sandbox if a crash is triggered. This vulnerability     affects Firefox ESR < 60.9, Firefox ESR < 68.1, and Firefox < 69. (CVE-2019-9812)

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

The version of Firefox ESR installed on the remote macOS or Mac OS X host is prior to 60.9. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2019-27 advisory.

  - Given a compromised sandboxed content process due to a separate vulnerability, it is possible to escape     that sandbox by loading <code>accounts.firefox.com</code> in that process and forcing a log-in to a     malicious Firefox Sync account. Preference settings that disable the sandbox are then synchronized to the     local machine and the compromised browser would restart without the sandbox if a crash is triggered.
    (CVE-2019-9812)

  - 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. (CVE-2019-11752)

  - 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. (CVE-2019-11746)

  - Some HTML elements, such as <code><title></code> and <code><textarea></code>, can contain     literal angle brackets without treating them as markup. It is possible to pass a literal closing tag to     <code>.innerHTML</code> 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. (CVE-2019-11744)

  - A same-origin policy violation occurs allowing the theft of cross-origin images through a combination of     SVG filters and a <code><canvas></code> 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.

The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4122-1 advisory.

    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)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

Multiple security issues have been found in the Mozilla Firefox web browser, which could potentially result in the execution of arbitrary code, cross-site scripting, bypass of the same-origin policy, sandbox escape, information disclosure or denial of service.

For Debian 8 'Jessie', these problems have been fixed in version 60.9.0esr-1~deb8u1.
