| CVE-2021-38507 | 2 Debian, Mozilla | 4 Debian Linux, Firefox, Firefox Esr and 1 more | 2022-02-22 | 4.3 MEDIUM | 6.5 MEDIUM |
| The Opportunistic Encryption feature of HTTP2 (RFC 8164) allows a connection to be transparently upgraded to TLS while retaining the visual properties of an HTTP connection, including being same-origin with unencrypted connections on port 80. However, if a second encrypted port on the same IP address (e.g. port 8443) did not opt-in to opportunistic encryption; a network attacker could forward a connection from the browser to port 443 to port 8443, causing the browser to treat the content of port 8443 as same-origin with HTTP. This was resolved by disabling the Opportunistic Encryption feature, which had low usage. This vulnerability affects Firefox < 94, Thunderbird < 91.3, and Firefox ESR < 91.3. | |||||

| CVE-2020-6794 | 2 Canonical, Mozilla | 2 Ubuntu Linux, Thunderbird | 2022-01-01 | 4.3 MEDIUM | 6.5 MEDIUM |
| 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-2020-6800 | 2 Canonical, Mozilla | 4 Ubuntu Linux, Firefox, Firefox Esr and 1 more | 2022-01-01 | 6.8 MEDIUM | 8.8 HIGH |
| 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-2020-6799 | 2 Microsoft, Mozilla | 3 Windows, Firefox, Firefox Esr | 2022-01-01 | 5.1 MEDIUM | 8.8 HIGH |
| Command line arguments could have been injected during Firefox invocation as a shell handler for certain unsupported file types. This required Firefox to be configured as the default handler for a given file type and for a file downloaded to be opened in a third party application that insufficiently sanitized URL data. In that situation, clicking a link in the third party application could have been used to retrieve and execute files whose location was supplied through command line arguments. Note: This issue only affects Windows operating systems and when Firefox is configured as the default handler for non-default filetypes. Other operating systems are unaffected. This vulnerability affects Firefox < 73 and Firefox < ESR68.5. | |||||
| CVE-2020-6793 | 1 Mozilla | 1 Thunderbird | 2022-01-01 | 4.3 MEDIUM | 6.5 MEDIUM |

| CVE-2021-43527 | 1 Mozilla | 2 Nss, Nss Esr | 2021-12-29 | 7.5 HIGH | 9.8 CRITICAL |
| NSS (Network Security Services) versions prior to 3.73 or 3.68.1 ESR are vulnerable to a heap overflow when handling DER-encoded DSA or RSA-PSS signatures. Applications using NSS for handling signatures encoded within CMS, S/MIME, PKCS \#7, or PKCS \#12 are likely to be impacted. Applications using NSS for certificate validation or other TLS, X.509, OCSP or CRL functionality may be impacted, depending on how they configure NSS. *Note: This vulnerability does NOT impact Mozilla Firefox.* However, email clients and PDF viewers that use NSS for signature verification, such as Thunderbird, LibreOffice, Evolution and Evince are believed to be impacted. This vulnerability affects NSS < 3.73 and NSS < 3.68.1. | |||||
| CVE-2020-12387 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2021-12-14 | 6.8 MEDIUM | 8.1 HIGH |
| 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-2021-38505 | 2 Microsoft, Mozilla | 4 Windows 10, Firefox, Firefox Esr and 1 more | 2021-12-10 | 4.3 MEDIUM | 6.5 MEDIUM |
| Microsoft introduced a new feature in Windows 10 known as Cloud Clipboard which, if enabled, will record data copied to the clipboard to the cloud, and make it available on other computers in certain scenarios. Applications that wish to prevent copied data from being recorded in Cloud History must use specific clipboard formats; and Firefox before versions 94 and ESR 91.3 did not implement them. This could have caused sensitive data to be recorded to a user's Microsoft account. *This bug only affects Firefox for Windows 10+ with Cloud Clipboard enabled. Other operating systems are unaffected.*. This vulnerability affects Firefox < 94, Thunderbird < 91.3, and Firefox ESR < 91.3. | |||||
| CVE-2021-43530 | 2 Google, Mozilla | 2 Android, Firefox | 2021-12-10 | 4.3 MEDIUM | 6.1 MEDIUM |
| A Universal XSS vulnerability was present in Firefox for Android resulting from improper sanitization when processing a URL scanned from a QR code. *This bug only affects Firefox for Android. Other operating systems are unaffected.*. This vulnerability affects Firefox < 94. | |||||
| CVE-2021-43531 | 1 Mozilla | 1 Firefox | 2021-12-10 | 4.3 MEDIUM | 4.3 MEDIUM |
| When a user loaded a Web Extensions context menu, the Web Extension could access the post-redirect URL of the element clicked. If the Web Extension lacked the WebRequest permission for the hosts involved in the redirect, this would be a same-origin-violation leaking data the Web Extension should have access to. This was fixed to provide the pre-redirect URL. This is related to CVE-2021-43532 but in the context of Web Extensions. This vulnerability affects Firefox < 94. | |||||
| CVE-2021-43532 | 1 Mozilla | 1 Firefox | 2021-12-10 | 5.8 MEDIUM | 6.1 MEDIUM |
| The 'Copy Image Link' context menu action would copy the final image URL after redirects. By embedding an image that triggered authentication flows - in conjunction with a Content Security Policy that stopped a redirection chain in the middle - the final image URL could be one that contained an authentication token used to takeover a user account. If a website tricked a user into copy and pasting the image link back to the page, the page would be able to steal the authentication tokens. This was fixed by making the action return the original URL, before any redirects. This vulnerability affects Firefox < 94. | |||||
| CVE-2021-43533 | 1 Mozilla | 1 Firefox | 2021-12-10 | 4.3 MEDIUM | 4.3 MEDIUM |
| When parsing internationalized domain names, high bits of the characters in the URLs were sometimes stripped, resulting in inconsistencies that could lead to user confusion or attacks such as phishing. This vulnerability affects Firefox < 94. | |||||
| CVE-2021-43544 | 2 Google, Mozilla | 2 Android, Firefox | 2021-12-10 | 4.3 MEDIUM | 6.1 MEDIUM |
| When receiving a URL through a SEND intent, Firefox would have searched for the text, but subsequent usages of the address bar might have caused the URL to load unintentionally, which could lead to XSS and spoofing attacks. *This bug only affects Firefox for Android. Other operating systems are unaffected.*. This vulnerability affects Firefox < 95. | |||||
| CVE-2021-29991 | 1 Mozilla | 2 Firefox, Thunderbird | 2021-11-04 | 5.8 MEDIUM | 8.1 HIGH |
| Firefox incorrectly accepted a newline in a HTTP/3 header, interpretting it as two separate headers. This allowed for a header splitting attack against servers using HTTP/3. This vulnerability affects Firefox < 91.0.1 and Thunderbird < 91.0.1. | |||||
| CVE-2021-29993 | 1 Mozilla | 1 Firefox | 2021-11-04 | 5.8 MEDIUM | 8.1 HIGH |
| Firefox for Android allowed navigations through the `intent://` protocol, which could be used to cause crashes and UI spoofs. *This bug only affects Firefox for Android. Other operating systems are unaffected.*. This vulnerability affects Firefox < 92. | |||||
