| A use-after-free could have occured when an HTTP2 session object was released on a different thread, leading to memory corruption and a potentially exploitable crash. This vulnerability affects Firefox < 93, Thunderbird < 91.3, and Firefox ESR < 91.3. | |||||
| CVE-2021-43534 | 2 Debian, Mozilla | 4 Debian Linux, Firefox, Firefox Esr and 1 more | 2024-11-21 | 6.8 MEDIUM | 8.8 HIGH |
| Mozilla developers and community members reported memory safety bugs present in Firefox 93 and Firefox ESR 91.2. 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 < 94, Thunderbird < 91.3, and Firefox ESR < 91.3. | |||||
| CVE-2021-43529 | 1 Mozilla | 1 Thunderbird | 2024-11-21 | N/A | 9.8 CRITICAL |
| Thunderbird versions prior to 91.3.0 are vulnerable to the heap overflow described in CVE-2021-43527 when processing S/MIME messages. Thunderbird versions 91.3.0 and later will not call the vulnerable code when processing S/MIME messages that contain certificates with DER-encoded DSA or RSA-PSS signatures. | |||||
| CVE-2021-43528 | 2 Debian, Mozilla | 2 Debian Linux, Thunderbird | 2024-11-21 | 4.3 MEDIUM | 6.5 MEDIUM |
| Thunderbird unexpectedly enabled JavaScript in the composition area. The JavaScript execution context was limited to this area and did not receive chrome-level privileges, but could be used as a stepping stone to further an attack with other vulnerabilities. This vulnerability affects Thunderbird < 91.4.0. | |||||
| CVE-2021-40529 | 3 Botan Project, Fedoraproject, Mozilla | 3 Botan, Fedora, Thunderbird | 2024-11-21 | 2.6 LOW | 5.9 MEDIUM |
| The ElGamal implementation in Botan through 2.18.1, as used in Thunderbird and other products, allows plaintext recovery because, during interaction between two cryptographic libraries, a certain dangerous combination of the prime defined by the receiver's public key, the generator defined by the receiver's public key, and the sender's ephemeral exponents can lead to a cross-configuration attack against OpenPGP. | |||||
| CVE-2021-38510 | 2 Apple, Mozilla | 4 Macos, Firefox, Firefox Esr and 1 more | 2024-11-21 | 6.8 MEDIUM | 8.8 HIGH |
| The executable file warning was not presented when downloading .inetloc files, which, due to a flaw in Mac OS, can run commands on a user's computer.*Note: This issue only affected Mac OS operating systems. Other operating systems are unaffected.*. This vulnerability affects Firefox < 94, Thunderbird < 91.3, and Firefox ESR < 91.3. | |||||
| CVE-2021-38509 | 2 Debian, Mozilla | 4 Debian Linux, Firefox, Firefox Esr and 1 more | 2024-11-21 | 4.3 MEDIUM | 4.3 MEDIUM |
| Due to an unusual sequence of attacker-controlled events, a Javascript alert() dialog with arbitrary (although unstyled) contents could be displayed over top an uncontrolled webpage of the attacker's choosing. This vulnerability affects Firefox < 94, Thunderbird < 91.3, and Firefox ESR < 91.3. | |||||
| CVE-2021-38508 | 2 Debian, Mozilla | 4 Debian Linux, Firefox, Firefox Esr and 1 more | 2024-11-21 | 4.3 MEDIUM | 4.3 MEDIUM |
| By displaying a form validity message in the correct location at the same time as a permission prompt (such as for geolocation), the validity message could have obscured the prompt, resulting in the user potentially being tricked into granting the permission. This vulnerability affects Firefox < 94, Thunderbird < 91.3, and Firefox ESR < 91.3. | |||||
| CVE-2021-38507 | 2 Debian, Mozilla | 4 Debian Linux, Firefox, Firefox Esr and 1 more | 2024-11-21 | 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-2021-38506 | 2 Debian, Mozilla | 4 Debian Linux, Firefox, Firefox Esr and 1 more | 2024-11-21 | 4.3 MEDIUM | 4.3 MEDIUM |
| Through a series of navigations, Firefox could have entered fullscreen mode without notification or warning to the user. This could lead to spoofing attacks on the browser UI including phishing. This vulnerability affects Firefox < 94, Thunderbird < 91.3, and Firefox ESR < 91.3. | |||||
| CVE-2021-38505 | 2 Microsoft, Mozilla | 4 Windows 10, Firefox, Firefox Esr and 1 more | 2024-11-21 | 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-2021-38504 | 2 Debian, Mozilla | 4 Debian Linux, Firefox, Firefox Esr and 1 more | 2024-11-21 | 6.8 MEDIUM | 8.8 HIGH |
| When interacting with an HTML input element's file picker dialog with webkitdirectory set, a use-after-free could have resulted, leading to memory corruption and a potentially exploitable crash. This vulnerability affects Firefox < 94, Thunderbird < 91.3, and Firefox ESR < 91.3. | |||||
| CVE-2021-38503 | 2 Debian, Mozilla | 4 Debian Linux, Firefox, Firefox Esr and 1 more | 2024-11-21 | 7.5 HIGH | 10.0 CRITICAL |
| The iframe sandbox rules were not correctly applied to XSLT stylesheets, allowing an iframe to bypass restrictions such as executing scripts or navigating the top-level frame. This vulnerability affects Firefox < 94, Thunderbird < 91.3, and Firefox ESR < 91.3. | |||||
| CVE-2021-38502 | 2 Debian, Mozilla | 2 Debian Linux, Thunderbird | 2024-11-21 | 4.3 MEDIUM | 5.9 MEDIUM |
| Thunderbird ignored the configuration to require STARTTLS security for an SMTP connection. A MITM could perform a downgrade attack to intercept transmitted messages, or could take control of the authenticated session to execute SMTP commands chosen by the MITM. If an unprotected authentication method was configured, the MITM could obtain the authentication credentials, too. This vulnerability affects Thunderbird < 91.2. | |||||
| CVE-2021-38501 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2024-11-21 | 6.8 MEDIUM | 8.8 HIGH |
| Mozilla developers reported memory safety bugs present in Firefox 92 and Firefox ESR 91.1.

| CVE-2021-38500 | 2 Debian, Mozilla | 4 Debian Linux, Firefox, Firefox Esr and 1 more | 2024-11-21 | 6.8 MEDIUM | 8.8 HIGH |
| Mozilla developers reported memory safety bugs present in Firefox 92 and Firefox ESR 91.1.

| During process shutdown, a document could have caused a use-after-free of a languages service object, leading to memory corruption and a potentially exploitable crash. This vulnerability affects Firefox < 93, Thunderbird < 91.2, and Firefox ESR < 91.2. | |||||
| CVE-2021-38497 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2024-11-21 | 4.3 MEDIUM | 6.5 MEDIUM |
| Through use of reportValidity() and window.open(), a plain-text validation message could have been overlaid on another origin, leading to possible user confusion and spoofing attacks. This vulnerability affects Firefox < 93, Thunderbird < 91.2, and Firefox ESR < 91.2. | |||||
| CVE-2021-38496 | 2 Debian, Mozilla | 4 Debian Linux, Firefox, Firefox Esr and 1 more | 2024-11-21 | 6.8 MEDIUM | 8.8 HIGH |
