Multiple security issues were discovered in Thunderbird. If a user were tricked in to opening a specially crafted website in a browsing context, an attacker could potentially exploit these to cause a denial of service, bypass same-origin protections, or execute arbitrary code.
(CVE-2019-18511, CVE-2019-11691, CVE-2019-11692, CVE-2019-11693, CVE-2019-9797, CVE-2019-9800, CVE-2019-9817, CVE-2019-9819, CVE-2019-9820)

Multiple security issues were discovered in Thunderbird. If a user were tricked in to opening a specially crafted message, an attacker could potentially exploit these to cause a denial of service, or execute arbitrary code. (CVE-2019-5798, CVE-2019-7317)

A type confusion bug was discovered with object groups and UnboxedObjects. If a user were tricked in to opening a specially crafted website in a browsing context after enabling the UnboxedObjects feature, an attacker could potentially exploit this to bypass security checks. (CVE-2019-9816)

It was discovered that history data could be exposed via drag and drop of hyperlinks to and from bookmarks. If a user were tricked in to dragging a specially crafted hyperlink to a bookmark toolbar or sidebar, and subsequently back in to the web content area, an attacker could potentially exploit this to obtain sensitive information.
(CVE-2019-11698).

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.

The remote Redhat Enterprise Linux 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2019:1269 advisory.

  - chromium-browser: Out of bounds read in Skia (CVE-2019-5798)

  - libpng: use-after-free in png_image_free in png.c (CVE-2019-7317)

  - Mozilla: Cross-origin theft of images with createImageBitmap (CVE-2019-9797)

  - Mozilla: Memory safety bugs fixed in Firefox 67 and Firefox ESR 60.7 (CVE-2019-9800)

  - Mozilla: Compartment mismatch with fetch API (CVE-2019-9819)

  - Mozilla: Use-after-free of ChromeEventHandler by DocShell (CVE-2019-9820)

  - Mozilla: Use-after-free in XMLHttpRequest (CVE-2019-11691)

  - Mozilla: Use-after-free removing listeners in the event listener manager (CVE-2019-11692)

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

Versions of Mozilla Firefox ESR earlier than 60.7 are unpatched for the following vulnerabilities:

 - 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 png_image_free 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)
