| CVE-2023-50761 | 2 Debian, Mozilla | 2 Debian Linux, Thunderbird | 2023-12-29 | N/A | 4.3 MEDIUM |
| The signature of a digitally signed S/MIME email message may optionally specify the signature creation date and time. If present, Thunderbird did not compare the signature creation date with the message date and time, and displayed a valid signature despite a date or time mismatch. This could be used to give recipients the impression that a message was sent at a different date or time. This vulnerability affects Thunderbird < 115.6. | |||||
| CVE-2023-50762 | 2 Debian, Mozilla | 2 Debian Linux, Thunderbird | 2023-12-29 | N/A | 4.3 MEDIUM |
| When processing a PGP/MIME payload that contains digitally signed text, the first paragraph of the text was never shown to the user. This is because the text was interpreted as a MIME message and the first paragraph was always treated as an email header section. A digitally signed text from a different context, such as a signed GIT commit, could be used to spoof an email message. This vulnerability affects Thunderbird < 115.6. | |||||
| CVE-2023-4421 | 1 Mozilla | 1 Nss | 2023-12-20 | N/A | 6.5 MEDIUM |
| The NSS code used for checking PKCS#1 v1.5 was leaking information useful in mounting Bleichenbacher-like attacks. Both the overall correctness of the padding as well as the length of the encrypted message was leaking through timing side-channel. By sending large number of attacker-selected ciphertexts, the attacker would be able to decrypt a previously intercepted PKCS#1 v1.5 ciphertext (for example, to decrypt a TLS session that used RSA key exchange), or forge a signature using the victim's key. The issue was fixed by implementing the implicit rejection algorithm, in which the NSS returns a deterministic random message in case invalid padding is detected, as proposed in the Marvin Attack paper. This vulnerability affects NSS < 3.61. | |||||
| CVE-2023-6204 | 2 Debian, Mozilla | 4 Debian Linux, Firefox, Firefox Esr and 1 more | 2023-11-30 | N/A | 6.5 MEDIUM |

| CVE-2023-6209 | 2 Debian, Mozilla | 4 Debian Linux, Firefox, Firefox Esr and 1 more | 2023-11-30 | N/A | 6.5 MEDIUM |
| Relative URLs starting with three slashes were incorrectly parsed, and a path-traversal "/../" part in the path could be used to override the specified host. This could contribute to security problems in web sites. This vulnerability affects Firefox < 120, Firefox ESR < 115.5.0, and Thunderbird < 115.5. | |||||
| CVE-2023-6205 | 2 Debian, Mozilla | 4 Debian Linux, Firefox, Firefox Esr and 1 more | 2023-11-30 | N/A | 6.5 MEDIUM |
| It was possible to cause the use of a MessagePort after it had already been freed, which could potentially have led to an exploitable crash. This vulnerability affects Firefox < 120, Firefox ESR < 115.5.0, and Thunderbird < 115.5. | |||||
| CVE-2023-6206 | 2 Debian, Mozilla | 4 Debian Linux, Firefox, Firefox Esr and 1 more | 2023-11-30 | N/A | 5.4 MEDIUM |
| The black fade animation when exiting fullscreen is roughly the length of the anti-clickjacking delay on permission prompts. It was possible to use this fact to surprise users by luring them to click where the permission grant button would be about to appear. This vulnerability affects Firefox < 120, Firefox ESR < 115.5.0, and Thunderbird < 115.5. | |||||
| CVE-2023-49061 | 1 Mozilla | 1 Firefox | 2023-11-28 | N/A | 6.1 MEDIUM |

| CVE-2023-4045 | 2 Debian, Mozilla | 3 Debian Linux, Firefox, Firefox Esr | 2023-08-09 | N/A | 5.3 MEDIUM |
| Offscreen Canvas did not properly track cross-origin tainting, which could have been used to access image data from another site in violation of same-origin policy. This vulnerability affects Firefox < 116, Firefox ESR < 102.14, and Firefox ESR < 115.1. | |||||
| CVE-2023-4049 | 2 Debian, Mozilla | 3 Debian Linux, Firefox, Firefox Esr | 2023-08-09 | N/A | 5.9 MEDIUM |

| CVE-2022-1520 | 1 Mozilla | 1 Thunderbird | 2023-08-08 | N/A | 4.3 MEDIUM |
| When viewing an email message A, which contains an attached message B, where B is encrypted or digitally signed or both, Thunderbird may show an incorrect encryption or signature status. After opening and viewing the attached message B, when returning to the display of message A, the message A might be shown with the security status of message B. This vulnerability affects Thunderbird < 91.9. | |||||
| CVE-2022-22757 | 1 Mozilla | 1 Firefox | 2023-08-08 | N/A | 6.5 MEDIUM |
| Remote Agent, used in WebDriver, did not validate the Host or Origin headers. This could have allowed websites to connect back locally to the user's browser to control it. <br>*This bug only affected Firefox when WebDriver was enabled, which is not the default configuration.*. This vulnerability affects Firefox < 97. | |||||
| CVE-2022-3032 | 1 Mozilla | 1 Thunderbird | 2023-08-08 | N/A | 6.5 MEDIUM |
| When receiving an HTML email that contained an <code>iframe</code> element, which used a <code>srcdoc</code> attribute to define the inner HTML document, remote objects specified in the nested document, for example images or videos, were not blocked. Rather, the network was accessed, the objects were loaded and displayed. This vulnerability affects Thunderbird < 102.2.1 and Thunderbird < 91.13.1. | |||||
| CVE-2022-31746 | 1 Mozilla | 1 Firefox | 2023-08-08 | N/A | 6.5 MEDIUM |

| CVE-2022-31744 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2023-08-08 | N/A | 6.5 MEDIUM |
| An attacker could have injected CSS into stylesheets accessible via internal URIs, such as resource:, and in doing so bypass a page's Content Security Policy. This vulnerability affects Firefox ESR < 91.11, Thunderbird < 102, Thunderbird < 91.11, and Firefox < 101. | |||||
| CVE-2021-23993 | 1 Mozilla | 1 Thunderbird | 2023-08-08 | 4.3 MEDIUM | 6.5 MEDIUM |
| An attacker may perform a DoS attack to prevent a user from sending encrypted email to a correspondent. If an attacker creates a crafted OpenPGP key with a subkey that has an invalid self signature, and the Thunderbird user imports the crafted key, then Thunderbird may try to use the invalid subkey, but the RNP library rejects it from being used, causing encryption to fail. This vulnerability affects Thunderbird < 78.9.1. | |||||
| CVE-2021-43536 | 2 Debian, Mozilla | 4 Debian Linux, Firefox, Firefox Esr and 1 more | 2023-08-08 | 4.3 MEDIUM | 6.5 MEDIUM |
| Under certain circumstances, asynchronous functions could have caused a navigation to fail but expose the target URL. This vulnerability affects Thunderbird < 91.4.0, Firefox ESR < 91.4.0, and Firefox < 95. | |||||
| CVE-2022-28285 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2023-08-08 | N/A | 6.5 MEDIUM |
| When generating the assembly code for <code>MLoadTypedArrayElementHole</code>, an incorrect AliasSet was used. In conjunction with another vulnerability this could have been used for an out of bounds memory read. This vulnerability affects Thunderbird < 91.8, Firefox < 99, and Firefox ESR < 91.8. | |||||
| CVE-2023-4054 | 2 Microsoft, Mozilla | 3 Windows, Firefox, Firefox Esr | 2023-08-07 | N/A | 5.5 MEDIUM |
| When opening appref-ms files, Firefox did not warn the user that these files may contain malicious code. *This bug only affects Firefox on Windows. Other operating systems are unaffected.* This vulnerability affects Firefox < 116, Firefox ESR < 102.14, Firefox ESR < 115.1, Thunderbird < 102.14, and Thunderbird < 115.1. | |||||
| CVE-2023-4052 | 1 Mozilla | 2 Firefox, Firefox Esr | 2023-08-07 | N/A | 6.5 MEDIUM |
| The Firefox updater created a directory writable by non-privileged users. When uninstalling Firefox, any files in that directory would be recursively deleted with the permissions of the uninstalling user account. This could be combined with creation of a junction (a form of symbolic link) to allow arbitrary file deletion controlled by the non-privileged user. *This bug only affects Firefox on Windows. Other operating systems are unaffected.* This vulnerability affects Firefox < 116, Firefox ESR < 115.1, and Thunderbird < 115.1. | |||||
| CVE-2023-4053 | 1 Mozilla | 1 Firefox | 2023-08-04 | N/A | 6.5 MEDIUM |
| A website could have obscured the full screen notification by using a URL with a scheme handled by an external program, such as a mailto URL. This could have led to user confusion and possible spoofing attacks. This vulnerability affects Firefox < 116. | |||||
