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)

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)

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)

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)

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)

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)

The remote Oracle Linux 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the ELSA-2019-2729 advisory.

    [60.9.0-1.0.1]

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.

    It was discovered that encrypted S/MIME parts in a multipart message can leak plaintext contents when     included in a HTML reply or forward in some circumstances. If a user were tricked in to replying to or     forwarding a specially crafted message, an attacker could potentially exploit this to obtain sensitive     information. (CVE-2019-11739)

    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 obtain sensitive     information, conduct cross-site scripting (XSS) attack, scause a denial of service, or execute arbitrary     code. (CVE-2019-11740, CVE-2019-11742, CVE-2019-11743, CVE-2019-11744, CVE-2019-11746, CVE-2019-11752)

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.

    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)
