  - Disable LTO (boo#1133267).

  - Add patch to fix build using rust-1.33: (boo#1130694)

The version of Firefox ESR installed on the remote Windows host is prior to 60.7. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2019-14 advisory.

  - If hyperthreading is not disabled, a timing attack     vulnerability exists, similar to previous Spectre     attacks. Apple has shipped macOS 10.14.5 with an option     to disable hyperthreading in applications running     untrusted code in a thread through a new sysctl. Firefox     now makes use of it on the main thread and any worker     threads. Note: users need to update to macOS 10.14.5     in order to take advantage of this change.
    (CVE-2019-9815)

  - A possible vulnerability exists where type confusion can     occur when manipulating JavaScript objects in object     groups, allowing for the bypassing of security checks     within these groups. Note: this vulnerability has     only been demonstrated with UnboxedObjects,     which are disabled by default on all supported releases.
    (CVE-2019-9816)

  - Images from a different domain can be read using a     canvas object in some circumstances. This could be used     to steal image data from a different site in violation     of same-origin policy. (CVE-2019-9817)

  - A race condition is present in the crash generation     server used to generate data for the crash reporter.
    This issue can lead to a use-after-free in the main     process, resulting in a potentially exploitable crash     and a sandbox escape. Note: this vulnerability only     affects Windows. Other operating systems are unaffected.
    (CVE-2019-9818)

  - A vulnerability where a JavaScript compartment mismatch     can occur while working with the fetch API,     resulting in a potentially exploitable crash.
    (CVE-2019-9819)

  - A use-after-free vulnerability can occur in the chrome     event handler when it is freed while still in use. This     results in a potentially exploitable crash.
    (CVE-2019-9820)

  - A use-after-free vulnerability can occur when working     with XMLHttpRequest (XHR) in an event loop,     causing the XHR main thread to be called after it has     been freed. This results in a potentially exploitable     crash. (CVE-2019-11691)

  - A use-after-free vulnerability can occur when listeners     are removed from the event listener manager while still     in use, resulting in a potentially exploitable crash.
    (CVE-2019-11692)

  - The bufferdata function in WebGL is     vulnerable to a buffer overflow with specific graphics     drivers on Linux. This could result in malicious content     freezing a tab or triggering a potentially exploitable     crash. Note: this issue only occurs on Linux. Other     operating systems are unaffected. (CVE-2019-11693)

  - A use-after-free vulnerability was discovered in the     pngimagefree function in the libpng     library. This could lead to denial of service or a     potentially exploitable crash when a malformed image is     processed. (CVE-2019-7317)

  - Cross-origin images can be read in violation of the     same-origin policy by exporting an image after using     createImageBitmap to read the image and     then rendering the resulting bitmap image within a     canvas element. (CVE-2019-9797)

  - Cross-origin images can be read from a     canvas element in violation of the same-     origin policy using the     transferFromImageBitmap method.
    (CVE-2018-18511)

  - A vulnerability exists in the Windows sandbox where an     uninitialized value in memory can be leaked to a     renderer from a broker when making a call to access an     otherwise unavailable file. This results in the     potential leaking of information stored at that memory     location. Note: this issue only occurs on Windows.
    Other operating systems are unaffected. (CVE-2019-11694)

  - If a crafted hyperlink is dragged and dropped to the     bookmark bar or sidebar and the resulting bookmark is     subsequently dragged and dropped into the web content     area, an arbitrary query of a user's browser history can     be run and transmitted to the content page via     drop event data. This allows for the theft     of browser history by a malicious site. (CVE-2019-11698)

  - An out-of-bounds read can occur in the Skia library     during path transformations. This could result in the     exposure of data stored in memory. (CVE-2019-5798)

  - Mozilla developers and community members Olli Pettay,     Bogdan Tara, Jan de Mooij, Jason Kratzer, Jan Varga,     Gary Kwong, Tim Guan-tin Chien, Tyson Smith, Ronald     Crane, and Ted Campbell reported memory safety bugs     present in Firefox 66 and Firefox ESR 60.6. 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. (CVE-2019-9800)

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 60.7. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2019-14 advisory.

    Other operating systems are unaffected. (CVE-2019-11694)

  - A custom cursor defined by scripting on a site can     position itself over the addressbar to spoof the actual     cursor when it should not be allowed outside of the     primary web content area. This could be used by a     malicious site to trick users into clicking on     permission prompts, doorhanger notifications, or other     buttons inadvertently if the location is spoofed over     the user interface. (CVE-2019-11695)

  - Files with the .JNLP extension used for     Java web start applications are not treated as     executable content for download prompts even though they     can be executed if Java is installed on the local     system. This could allow users to mistakenly launch an     executable binary locally. (CVE-2019-11696)

  - If the ALT and a keys are pressed when     users receive an extension installation prompt, the     extension will be installed without the install prompt     delay that keeps the prompt visible in order for users     to accept or decline the installation. A malicious web     page could use this with spoofing on the page to trick     users into installing a malicious extension.
    (CVE-2019-11697)

  - If a crafted hyperlink is dragged and dropped to the     bookmark bar or sidebar and the resulting bookmark is     subsequently dragged and dropped into the web content     area, an arbitrary query of a user's browser history can     be run and transmitted to the content page via     drop event data. This allows for the theft     of browser history by a malicious site. (CVE-2019-11698)

  - A hyperlink using the res: protocol can be     used to open local files at a known location in Internet     Explorer if a user approves execution when prompted.
    Note: this issue only occurs on Windows. Other     operating systems are unaffected. (CVE-2019-11700)

  - A malicious page can briefly cause the wrong name to be     highlighted as the domain name in the addressbar during     page navigations. This could result in user confusion of     which site is currently loaded for spoofing attacks.
    (CVE-2019-11699)

  - The default webcal: protocol handler will     load a web site vulnerable to cross-site scripting (XSS)     attacks. This default was left in place as a legacy     feature and has now been removed. Note: this issue     only affects users with an account on the vulnerable     service. Other users are unaffected. (CVE-2019-11701)

  - Mozilla developers and community members Christian     Holler, Andrei Ciure, Julien Cristau, Jan de Mooij, Jan     Varga, Marcia Knous, Andr Bargull, and Philipp reported     memory safety bugs present in Firefox 66.

The version of Thunderbird installed on the remote Windows host is prior to 60.7. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2019-15 advisory.

  - If hyperthreading is not disabled, a timing attack     vulnerability exists, similar to previous Spectre     attacks. Apple has shipped macOS 10.14.5 with an option     to disable hyperthreading in applications running     untrusted code in a thread through a new sysctl. Firefox     now makes use of it on the main thread and any worker     threads. Note: users need to update to macOS 10.14.5     in order to take advantage of this change.
    (CVE-2019-9815)

  - A possible vulnerability exists where type confusion can     occur when manipulating JavaScript objects in object     groups, allowing for the bypassing of security checks     within these groups. Note: this vulnerability has     only been demonstrated with UnboxedObjects,     which are disabled by default on all supported releases.
    (CVE-2019-9816)

  - Images from a different domain can be read using a     canvas object in some circumstances. This could be used     to steal image data from a different site in violation     of same-origin policy. (CVE-2019-9817)

  - A race condition is present in the crash generation     server used to generate data for the crash reporter.
    This issue can lead to a use-after-free in the main     process, resulting in a potentially exploitable crash     and a sandbox escape. Note: this vulnerability only     affects Windows. Other operating systems are unaffected.
    (CVE-2019-9818)

  - A vulnerability where a JavaScript compartment mismatch     can occur while working with the fetch API,     resulting in a potentially exploitable crash.
    (CVE-2019-9819)

  - A use-after-free vulnerability can occur in the chrome     event handler when it is freed while still in use. This     results in a potentially exploitable crash.
    (CVE-2019-9820)

  - A use-after-free vulnerability can occur when working     with XMLHttpRequest (XHR) in an event loop,     causing the XHR main thread to be called after it has     been freed. This results in a potentially exploitable     crash. (CVE-2019-11691)

  - A use-after-free vulnerability can occur when listeners     are removed from the event listener manager while still     in use, resulting in a potentially exploitable crash.
    (CVE-2019-11692)

  - The bufferdata function in WebGL is     vulnerable to a buffer overflow with specific graphics     drivers on Linux. This could result in malicious content     freezing a tab or triggering a potentially exploitable     crash. Note: this issue only occurs on Linux. Other     operating systems are unaffected. (CVE-2019-11693)

  - A use-after-free vulnerability was discovered in the     pngimagefree function in the libpng     library. This could lead to denial of service or a     potentially exploitable crash when a malformed image is     processed. (CVE-2019-7317)

  - Cross-origin images can be read in violation of the     same-origin policy by exporting an image after using     createImageBitmap to read the image and     then rendering the resulting bitmap image within a     canvas element. (CVE-2019-9797)

  - Cross-origin images can be read from a     canvas element in violation of the same-     origin policy using the     transferFromImageBitmap method.
    (CVE-2018-18511)

  - A vulnerability exists in the Windows sandbox where an     uninitialized value in memory can be leaked to a     renderer from a broker when making a call to access an     otherwise unavailable file. This results in the     potential leaking of information stored at that memory     location. Note: this issue only occurs on Windows.
    Other operating systems are unaffected. (CVE-2019-11694)

  - If a crafted hyperlink is dragged and dropped to the     bookmark bar or sidebar and the resulting bookmark is     subsequently dragged and dropped into the web content     area, an arbitrary query of a user's browser history can     be run and transmitted to the content page via     drop event data. This allows for the theft     of browser history by a malicious site. (CVE-2019-11698)

  - An out-of-bounds read can occur in the Skia library     during path transformations. This could result in the     exposure of data stored in memory. (CVE-2019-5798)

  - Mozilla developers and community members Olli Pettay,     Bogdan Tara, Jan de Mooij, Jason Kratzer, Jan Varga,     Gary Kwong, Tim Guan-tin Chien, Tyson Smith, Ronald     Crane, and Ted Campbell reported memory safety bugs     present in Firefox 66, Firefox ESR 60.6, and Thunderbird     60.6.
