| CVE-2021-43528 | 2 Debian, Mozilla | 2 Debian Linux, Thunderbird | 2024-02-28 | 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-2021-43542 | 2 Debian, Mozilla | 4 Debian Linux, Firefox, Firefox Esr and 1 more | 2024-02-28 | 4.3 MEDIUM | 6.5 MEDIUM |
| Using XMLHttpRequest, an attacker could have identified installed applications by probing error messages for loading external protocols. This vulnerability affects Thunderbird < 91.4.0, Firefox ESR < 91.4.0, and Firefox < 95. | |||||
| CVE-2021-43532 | 1 Mozilla | 1 Firefox | 2024-02-28 | 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. | |||||

| Mozilla developers reported memory safety bugs present in Thunderbird 78.13.0. 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 Thunderbird < 91.1 and Firefox ESR < 91.1. | |||||
| CVE-2021-38492 | 2 Microsoft, Mozilla | 4 Windows, Firefox, Firefox Esr and 1 more | 2024-02-28 | 4.3 MEDIUM | 6.5 MEDIUM |
| When delegating navigations to the operating system, Firefox would accept the `mk` scheme which might allow attackers to launch pages and execute scripts in Internet Explorer in unprivileged mode. *This bug only affects Firefox for Windows. Other operating systems are unaffected.*. This vulnerability affects Firefox < 92, Thunderbird < 91.1, Thunderbird < 78.14, Firefox ESR < 78.14, and Firefox ESR < 91.1. | |||||
| CVE-2021-43544 | 2 Google, Mozilla | 2 Android, Firefox | 2024-02-28 | 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-2021-38494 | 1 Mozilla | 1 Firefox | 2024-02-28 | 6.8 MEDIUM | 8.8 HIGH |
| Mozilla developers reported memory safety bugs present in Firefox 91. 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 < 92. | |||||
| CVE-2021-38499 | 1 Mozilla | 1 Firefox | 2024-02-28 | 6.8 MEDIUM | 8.8 HIGH |

| 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-2021-43533 | 1 Mozilla | 1 Firefox | 2024-02-28 | 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. | |||||

| 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 | 2024-02-28 | 6.8 MEDIUM | 8.8 HIGH |
| Mozilla developers reported memory safety bugs present in Firefox 92 and Firefox ESR 91.1.

| CVE-2021-43527 | 4 Mozilla, Netapp, Oracle and 1 more | 10 Nss, Nss Esr, Cloud Backup and 7 more | 2024-02-28 | 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. | |||||
