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

  - When removing data about an origin whose tab was recently closed, a use-after-free could occur in the     Quota manager, resulting in a potentially exploitable crash. This vulnerability affects Thunderbird <     68.6, Firefox < 74, Firefox < ESR68.6, and Firefox ESR < 68.6. (CVE-2020-6805)

  - By carefully crafting promise resolutions, it was possible to cause an out-of-bounds read off the end of     an array resized during script execution. This could have led to memory corruption and a potentially     exploitable crash. This vulnerability affects Thunderbird < 68.6, Firefox < 74, Firefox < ESR68.6, and     Firefox ESR < 68.6. (CVE-2020-6806)

  - When pasting a <style> tag from the clipboard into a rich text editor, the CSS sanitizer does not     escape < and > characters. Because the resulting string is pasted directly into the text node of the     element this does not result in a direct injection into the webpage; however, if a webpage subsequently     copies the node's innerHTML, assigning it to another innerHTML, this would result in an XSS vulnerability.
    Two WYSIWYG editors were identified with this behavior, more may exist. This vulnerability affects Firefox     ESR < 68.4 and Firefox < 72. (CVE-2019-17022)

  - When pasting a <style> tag from the clipboard into a rich text editor, the CSS sanitizer incorrectly     rewrites a @namespace rule. This could allow for injection into certain types of websites resulting in     data exfiltration. This vulnerability affects Firefox ESR < 68.4 and Firefox < 72. (CVE-2019-17016)

  - Due to a missing case handling object types, a type confusion vulnerability could occur, resulting in a     crash. We presume that with enough effort that it could be exploited to run arbitrary code. This     vulnerability affects Firefox ESR < 68.4 and Firefox < 72. (CVE-2019-17017)

  - Mozilla developers reported memory safety bugs present in Firefox 71 and Firefox ESR 68.3. Some of these     bugs showed evidence of memory corruption and we presume that with enough effort some of these could have     been exploited to run arbitrary code. This vulnerability affects Firefox ESR < 68.4 and Firefox < 72.
    (CVE-2019-17024)

  - Incorrect alias information in IonMonkey JIT compiler for setting array elements could lead to a type     confusion. We are aware of targeted attacks in the wild abusing this flaw. This vulnerability affects     Firefox ESR < 68.4.1, Thunderbird < 68.4.1, and Firefox < 72.0.1. (CVE-2019-17026)

  - When processing an email message with an ill-formed envelope, Thunderbird could read data from a random     memory location. This vulnerability affects Thunderbird < 68.5. (CVE-2020-6793)

  - When processing a message that contains multiple S/MIME signatures, a bug in the MIME processing code     caused a null pointer dereference, leading to an unexploitable crash. This vulnerability affects     Thunderbird < 68.5. (CVE-2020-6795)

  - When deriving an identifier for an email message, uninitialized memory was used in addition to the message     contents. This vulnerability affects Thunderbird < 68.5. (CVE-2020-6792)

  - If a template tag was used in a select tag, the parser could be confused and allow JavaScript parsing and     execution when it should not be allowed. A site that relied on the browser behaving correctly could suffer     a cross-site scripting vulnerability as a result. In general, this flaw cannot be exploited through email     in the Thunderbird product because scripting is disabled when reading mail, but is potentially a risk in     browser or browser-like contexts. This vulnerability affects Thunderbird < 68.5, Firefox < 73, and Firefox     < ESR68.5. (CVE-2020-6798)

  - Mozilla developers and community members reported memory safety bugs present in Firefox 72 and Firefox ESR     68.4. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some     of these could have been exploited to run arbitrary code. In general, these flaws cannot be exploited     through email in the Thunderbird product because scripting is disabled when reading mail, but are     potentially risks in browser or browser-like contexts. This vulnerability affects Thunderbird < 68.5,     Firefox < 73, and Firefox < ESR68.5. (CVE-2020-6800)

  - If a user saved passwords before Thunderbird 60 and then later set a master password, an unencrypted copy     of these passwords is still accessible. This is because the older stored password file was not deleted     when the data was copied to a new format starting in Thunderbird 60. The new master password is added only     on the new file. This could allow the exposure of stored password data outside of user expectations. This     vulnerability affects Thunderbird < 68.5. (CVE-2020-6794)

  - The 'Copy as cURL' feature of Devtools' network tab did not properly escape the HTTP method of a request,     which can be controlled by the website. If a user used the 'Copy as Curl' feature and pasted the command     into a terminal, it could have resulted in command injection and arbitrary command execution. This     vulnerability affects Thunderbird < 68.6, Firefox < 74, Firefox < ESR68.6, and Firefox ESR < 68.6.
    (CVE-2020-6811)

  - usrsctp before 2019-12-20 has out-of-bounds reads in sctp_load_addresses_from_init. (CVE-2019-20503)

  - The first time AirPods are connected to an iPhone, they become named after the user's name by default     (e.g. Jane Doe's AirPods.) Websites with camera or microphone permission are able to enumerate device     names, disclosing the user's name. To resolve this issue, Firefox added a special case that renames     devices containing the substring 'AirPods' to simply 'AirPods'. This vulnerability affects Thunderbird <     68.6, Firefox < 74, Firefox < ESR68.6, and Firefox ESR < 68.6. (CVE-2020-6812)

  - When a device was changed while a stream was about to be destroyed, the stream-reinit task     may have been executed after the stream was destroyed, causing a use-after-free and a potentially     exploitable crash. This vulnerability affects Thunderbird < 68.6, Firefox < 74, Firefox < ESR68.6, and     Firefox ESR < 68.6. (CVE-2020-6807)

  - Mozilla developers reported memory safety bugs present in Firefox and Thunderbird 68.5. Some of these bugs     showed evidence of memory corruption and we presume that with enough effort some of these could have been     exploited to run arbitrary code. This vulnerability affects Thunderbird < 68.6, Firefox < 74, Firefox <     ESR68.6, and Firefox ESR < 68.6. (CVE-2020-6814)

  - Under certain conditions, when running the nsDocShell destructor, a race condition can cause a use-after-     free. We are aware of targeted attacks in the wild abusing this flaw. This vulnerability affects     Thunderbird < 68.7.0, Firefox < 74.0.1, and Firefox ESR < 68.6.1. (CVE-2020-6819)

  - Under certain conditions, when handling a ReadableStream, a race condition can cause a use-after-free. We     are aware of targeted attacks in the wild abusing this flaw. This vulnerability affects Thunderbird <     68.7.0, Firefox < 74.0.1, and Firefox ESR < 68.6.1. (CVE-2020-6820)

  - When reading from areas partially or fully outside the source resource with WebGL's     copyTexSubImage method, the specification requires the returned values be zero. Previously,     this memory was uninitialized, leading to potentially sensitive data disclosure. This vulnerability     affects Thunderbird < 68.7.0, Firefox ESR < 68.7, and Firefox < 75. (CVE-2020-6821)

  - On 32-bit builds, an out of bounds write could have occurred when processing an image larger than 4 GB in     GMPDecodeData. It is possible that with enough effort this could have been exploited to run     arbitrary code. This vulnerability affects Thunderbird < 68.7.0, Firefox ESR < 68.7, and Firefox < 75.
    (CVE-2020-6822)

  - Mozilla developers and community members Tyson Smith and Christian Holler reported memory safety bugs     present in Firefox 74 and Firefox ESR 68.6. Some of these bugs showed evidence of memory corruption and we     presume that with enough effort some of these could have been exploited to run arbitrary code. This     vulnerability affects Thunderbird < 68.7.0, Firefox ESR < 68.7, and Firefox < 75. (CVE-2020-6825)

  - A race condition when running shutdown code for Web Worker led to a use-after-free vulnerability. This     resulted in a potentially exploitable crash. This vulnerability affects Firefox ESR < 68.8, Firefox < 76,     and Thunderbird < 68.8.0. (CVE-2020-12387)

  - A buffer overflow could occur when parsing and validating SCTP chunks in WebRTC. This could have led to     memory corruption and a potentially exploitable crash. This vulnerability affects Firefox ESR < 68.8,     Firefox < 76, and Thunderbird < 68.8.0. (CVE-2020-6831)

  - The 'Copy as cURL' feature of Devtools' network tab did not properly escape the HTTP POST data of a     request, which can be controlled by the website. If a user used the 'Copy as cURL' feature and pasted the     command into a terminal, it could have resulted in the disclosure of local files. This vulnerability     affects Firefox ESR < 68.8, Firefox < 76, and Thunderbird < 68.8.0. (CVE-2020-12392)

  - Mozilla developers and community members reported memory safety bugs present in Firefox 75 and Firefox ESR     68.7. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some     of these could have been exploited to run arbitrary code. This vulnerability affects Firefox ESR < 68.8,     Firefox < 76, and Thunderbird < 68.8.0. (CVE-2020-12395)

  - By encoding Unicode whitespace characters within the From email header, an attacker can spoof the sender     email address that Thunderbird displays. This vulnerability affects Thunderbird < 68.8.0. (CVE-2020-12397)
