The remote NewStart CGSL host, running version MAIN 6.02, has thunderbird packages installed that are affected by multiple vulnerabilities:

  - Due to confusion about ValueTags on JavaScript Objects, an object may pass through the type barrier,     resulting in memory corruption and a potentially exploitable crash. *Note: this issue only affects Firefox     on ARM64 platforms.* This vulnerability affects Firefox ESR < 68.10, Firefox < 78, and Thunderbird <     68.10.0. (CVE-2020-12417)

  - Manipulating individual parts of a URL object could have caused an out-of-bounds read, leaking process     memory to malicious JavaScript. This vulnerability affects Firefox ESR < 68.10, Firefox < 78, and     Thunderbird < 68.10.0. (CVE-2020-12418)

  - When processing callbacks that occurred during window flushing in the parent process, the associated     window may die; causing a use-after-free condition. This could have led to memory corruption and a     potentially exploitable crash. This vulnerability affects Firefox ESR < 68.10, Firefox < 78, and     Thunderbird < 68.10.0. (CVE-2020-12419)

  - When trying to connect to a STUN server, a race condition could have caused a use-after-free of a pointer,     leading to memory corruption and a potentially exploitable crash. This vulnerability affects Firefox ESR <     68.10, Firefox < 78, and Thunderbird < 68.10.0. (CVE-2020-12420)

  - When performing add-on updates, certificate chains terminating in non-built-in-roots were rejected (even     if they were legitimately added by an administrator.) This could have caused add-ons to become out-of-date     silently without notification to the user. This vulnerability affects Firefox ESR < 68.10, Firefox < 78,     and Thunderbird < 68.10.0. (CVE-2020-12421)

  - Use after free in ANGLE in Google Chrome prior to 81.0.4044.122 allowed a remote attacker to potentially     exploit heap corruption via a crafted HTML page. (CVE-2020-6463)

  - Inappropriate implementation in WebRTC in Google Chrome prior to 84.0.4147.89 allowed an attacker in a     privileged network position to potentially exploit heap corruption via a crafted SCTP stream.
    (CVE-2020-6514)

  - By observing the stack trace for JavaScript errors in web workers, it was possible to leak the result of a     cross-origin redirect. This applied only to content that can be parsed as script. This vulnerability     affects Firefox < 79, Firefox ESR < 68.11, Firefox ESR < 78.1, Thunderbird < 68.11, and Thunderbird <     78.1. (CVE-2020-15652)

  - Mozilla developers and community members reported memory safety bugs present in Firefox 78 and Firefox ESR     78.0. 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 < 79, Firefox     ESR < 68.11, Firefox ESR < 78.1, Thunderbird < 68.11, and Thunderbird < 78.1. (CVE-2020-15659)

  - By holding a reference to the eval() function from an about:blank window, a malicious webpage could have     gained access to the InstallTrigger object which would allow them to prompt the user to install an     extension. Combined with user confusion, this could result in an unintended or malicious extension being     installed. This vulnerability affects Firefox < 80, Thunderbird < 78.2, Thunderbird < 68.12, Firefox ESR <     68.12, Firefox ESR < 78.2, and Firefox for Android < 80. (CVE-2020-15664)

  - When aborting an operation, such as a fetch, an abort signal may be deleted while alerting the objects to     be notified. This results in a use-after-free and we presume that with enough effort it could have been     exploited to run arbitrary code. This vulnerability affects Firefox ESR < 68.12 and Thunderbird < 68.12.
    (CVE-2020-15669)

  - If an attacker intercepts Thunderbird's initial attempt to perform automatic account setup using the     Microsoft Exchange autodiscovery mechanism, and the attacker sends a crafted response, then Thunderbird     sends username and password over https to a server controlled by the attacker. This vulnerability affects     Thunderbird < 68.10.0. (CVE-2020-15646)

  - When aborting an operation, such as a fetch, an abort signal may be deleted while alerting the objects to     be notified. This results in a use-after-free and we presume that with enough effort it could have been     exploited to run arbitrary code. This vulnerability affects Firefox ESR < 68.12 and Thunderbird < 68.12.
    (CVE-2020-15669)

  - Mozilla developers reported memory safety bugs present in Firefox 80 and Firefox ESR 78.2. 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 < 81, Thunderbird < 78.3, and     Firefox ESR < 78.3. (CVE-2020-15673)

  - Firefox sometimes ran the onload handler for SVG elements that the DOM sanitizer decided to remove,     resulting in JavaScript being executed after pasting attacker-controlled data into a contenteditable     element. This vulnerability affects Firefox < 81, Thunderbird < 78.3, and Firefox ESR < 78.3.
    (CVE-2020-15676)

  - By exploiting an Open Redirect vulnerability on a website, an attacker could have spoofed the site     displayed in the download file dialog to show the original site (the one suffering from the open redirect)     rather than the site the file was actually downloaded from. This vulnerability affects Firefox < 81,     Thunderbird < 78.3, and Firefox ESR < 78.3. (CVE-2020-15677)

  - When recursing through graphical layers while scrolling, an iterator may have become invalid, resulting in     a potential use-after-free. This occurs because the function     APZCTreeManager::ComputeClippedCompositionBounds did not follow iterator invalidation rules. This     vulnerability affects Firefox < 81, Thunderbird < 78.3, and Firefox ESR < 78.3. (CVE-2020-15678)

  - Mozilla developers and community members reported memory safety bugs present in Firefox 81 and Firefox ESR     78.3. 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.

  - Side-channel information leakage in graphics in Google Chrome prior to 87.0.4280.66 allowed a remote     attacker to leak cross-origin data via a crafted HTML page. (CVE-2020-16012)

  - Uninitialized Use in V8 in Google Chrome prior to 87.0.4280.88 allowed a remote attacker to obtain     potentially sensitive information from process memory via a crafted HTML page. (CVE-2020-16042)

  - In certain circumstances, the MCallGetProperty opcode can be emitted with unmet assumptions resulting in     an exploitable use-after-free condition. This vulnerability affects Firefox < 82.0.3, Firefox ESR <     78.4.1, and Thunderbird < 78.4.2. (CVE-2020-26950)

  - A parsing and event loading mismatch in Firefox's SVG code could have allowed load events to fire, even     after sanitization. An attacker already capable of exploiting an XSS vulnerability in privileged internal     pages could have used this attack to bypass our built-in sanitizer. This vulnerability affects Firefox <     83, Firefox ESR < 78.5, and Thunderbird < 78.5. (CVE-2020-26951)

  - It was possible to cause the browser to enter fullscreen mode without displaying the security UI; thus     making it possible to attempt a phishing attack or otherwise confuse the user. This vulnerability affects     Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5. (CVE-2020-26953)

  - In some cases, removing HTML elements during sanitization would keep existing SVG event handlers and     therefore lead to XSS. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird <     78.5. (CVE-2020-26956)

  - Firefox did not block execution of scripts with incorrect MIME types when the response was intercepted and     cached through a ServiceWorker. This could lead to a cross-site script inclusion vulnerability, or a     Content Security Policy bypass. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and     Thunderbird < 78.5. (CVE-2020-26958)

  - During browser shutdown, reference decrementing could have occured on a previously freed object, resulting     in a use-after-free, memory corruption, and a potentially exploitable crash. This vulnerability affects     Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5. (CVE-2020-26959)

  - If the Compact() method was called on an nsTArray, the array could have been reallocated without updating     other pointers, leading to a potential use-after-free and exploitable crash. This vulnerability affects     Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5. (CVE-2020-26960)

  - When DNS over HTTPS is in use, it intentionally filters RFC1918 and related IP ranges from the responses     as these do not make sense coming from a DoH resolver. However when an IPv4 address was mapped through     IPv6, these addresses were erroneously let through, leading to a potential DNS Rebinding attack. This     vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5. (CVE-2020-26961)

  - Some websites have a feature Show Password where clicking a button will change a password field into a     textbook field, revealing the typed password. If, when using a software keyboard that remembers user     input, a user typed their password and used that feature, the type of the password field was changed,     resulting in a keyboard layout change and the possibility for the software keyboard to remember the typed     password. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5.
    (CVE-2020-26965)

  - Mozilla developers reported memory safety bugs present in Firefox 82 and Firefox ESR 78.4. 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. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and     Thunderbird < 78.5. (CVE-2020-26968)

  - When reading SMTP server status codes, Thunderbird writes an integer value to a position on the stack that     is intended to contain just one byte. Depending on processor architecture and stack layout, this leads to     stack corruption that may be exploitable. This vulnerability affects Thunderbird < 78.5.1.
    (CVE-2020-26970)

  - Certain blit values provided by the user were not properly constrained leading to a heap buffer overflow     on some video drivers. This vulnerability affects Firefox < 84, Thunderbird < 78.6, and Firefox ESR <     78.6. (CVE-2020-26971)

  - Certain input to the CSS Sanitizer confused it, resulting in incorrect components being removed. This     could have been used as a sanitizer bypass. This vulnerability affects Firefox < 84, Thunderbird < 78.6,     and Firefox ESR < 78.6. (CVE-2020-26973)

  - When flex-basis was used on a table wrapper, a StyleGenericFlexBasis object could have been incorrectly     cast to the wrong type. This resulted in a heap user-after-free, memory corruption, and a potentially     exploitable crash. This vulnerability affects Firefox < 84, Thunderbird < 78.6, and Firefox ESR < 78.6.
    (CVE-2020-26974)

  - Using techniques that built on the slipstream research, a malicious webpage could have exposed both an     internal network's hosts as well as services running on the user's local machine. This vulnerability     affects Firefox < 84, Thunderbird < 78.6, and Firefox ESR < 78.6. (CVE-2020-26978)

  - When an extension with the proxy permission registered to receive <all_urls>, the proxy.onRequest callback     was not triggered for view-source URLs. While web content cannot navigate to such URLs, a user opening     View Source could have inadvertently leaked their IP address. This vulnerability affects Firefox < 84,     Thunderbird < 78.6, and Firefox ESR < 78.6. (CVE-2020-35111)

  - Mozilla developers reported memory safety bugs present in Firefox 83 and Firefox ESR 78.5. 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 Firefox < 84, Thunderbird < 78.6, and     Firefox ESR < 78.6. (CVE-2020-35113)
