    CVE(s):
    CVE-2021-23968
    If Content Security Policy blocked frame navigation, the full destination of a redirect served in the
    frame was reported in the violation report; as opposed to the original frame URI. This could be used to
    leak sensitive information contained in such URIs. This vulnerability affects Firefox < 86, Thunderbird <
    78.8, and Firefox ESR < 78.8.
    CVE-2021-23969
    As specified in the W3C Content Security Policy draft, when creating a violation report, User agents need
    to ensure that the source file is the URL requested by the page, pre-redirects. If thats not possible,
    user agents need to strip the URL down to an origin to avoid unintentional leakage. Under certain types
    of redirects, Firefox incorrectly set the source file to be the destination of the redirects. This was
    fixed to be the redirect destination's origin. This vulnerability affects Firefox < 86, Thunderbird <
    78.8, and Firefox ESR < 78.8.
    CVE-2021-23973
    When trying to load a cross-origin resource in an audio/video context a decoding error may have resulted,
    and the content of that error may have revealed information about the resource. This vulnerability affects
    Firefox < 86, Thunderbird < 78.8, and Firefox ESR < 78.8.
    CVE-2021-23978
    Mozilla developers reported memory safety bugs present in Firefox 85 and Firefox ESR 78.7. 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 < 86, Thunderbird < 78.8, and
    Firefox ESR < 78.8.
    CVE-2020-15685
    ** RESERVED ** This candidate has been reserved by an organization or individual that will use it when
    announcing a new security problem. When the candidate has been publicized, the details for this candidate
    will be provided.
    CVE-2020-26976
    When a HTTPS pages was embedded in a HTTP page, and there was a service worker registered for the former,
    the service worker could have intercepted the request for the secure page despite the iframe not being a
    secure context due to the (insecure) framing. This vulnerability affects Firefox < 84.
    CVE-2021-23953
    If a user clicked into a specifically crafted PDF, the PDF reader could be confused into leaking cross-
    origin information, when said information is served as chunked data. This vulnerability affects Firefox <
    85, Thunderbird < 78.7, and Firefox ESR < 78.7.
    CVE-2021-23954
    Using the new logical assignment operators in a JavaScript switch statement could have caused a type
    confusion, leading to a memory corruption and a potentially exploitable crash. This vulnerability affects
    Firefox < 85, Thunderbird < 78.7, and Firefox ESR < 78.7.
    CVE-2021-23960
    Performing garbage collection on re-declared JavaScript variables resulted in a user-after-poison, and a
    potentially exploitable crash. This vulnerability affects Firefox < 85, Thunderbird < 78.7, and Firefox
    ESR < 78.7.
    CVE-2021-23964
    Mozilla developers reported memory safety bugs present in Firefox 84 and Firefox ESR 78.6. 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 Firefox < 85, Thunderbird < 78.7, and
    Firefox ESR < 78.7.
    CVE-2020-16044
    Use after free in WebRTC in Google Chrome prior to 88.0.4324.96 allowed a remote attacker to potentially
    exploit heap corruption via a crafted SCTP packet.
    CVE-2020-16042
    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-2020-26971
    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-2020-26973
    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-2020-26974
    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-2020-26978
    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-2020-35111
    When an extension with the proxy permission registered to receive , 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-2020-35113
    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-2020-26970
    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-2020-16012
    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-2020-26951
    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-2020-26953
    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-2020-26956
    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-2020-26958
    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-2020-26959
    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-2020-26960
    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-2020-26961
    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-2020-26965
    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-2020-26968
    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-2020-26950
    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.
