| CVE-2021-29951 | 2 Microsoft, Mozilla | 4 Windows, Firefox, Firefox Esr and 1 more | 2024-11-21 | 6.4 MEDIUM | 6.5 MEDIUM |
| The Mozilla Maintenance Service granted SERVICE_START access to BUILTIN|Users which, in a domain network, grants normal remote users access to start or stop the service. This could be used to prevent the browser update service from operating (if an attacker spammed the 'Stop' command); but also exposed attack surface in the maintenance service. *Note: This issue only affected Windows operating systems older than Win 10 build 1709. Other operating systems are unaffected.*. This vulnerability affects Thunderbird < 78.10.1, Firefox < 87, and Firefox ESR < 78.10.1. | |||||
| CVE-2021-29950 | 1 Mozilla | 1 Thunderbird | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| Thunderbird unprotects a secret OpenPGP key prior to using it for a decryption, signing or key import task. If the task runs into a failure, the secret key may remain in memory in its unprotected state. This vulnerability affects Thunderbird < 78.8.1. | |||||
| CVE-2021-29949 | 1 Mozilla | 1 Thunderbird | 2024-11-21 | 4.4 MEDIUM | 7.8 HIGH |
| When loading the shared library that provides the OTR protocol implementation, Thunderbird will initially attempt to open it using a filename that isn't distributed by Thunderbird. If a computer has already been infected with a malicious library of the alternative filename, and the malicious library has been copied to a directory that is contained in the search path for executable libraries, then Thunderbird will load the incorrect library. This vulnerability affects Thunderbird < 78.9.1. | |||||
| CVE-2021-29948 | 1 Mozilla | 1 Thunderbird | 2024-11-21 | 1.9 LOW | 2.5 LOW |
| Signatures are written to disk before and read during verification, which might be subject to a race condition when a malicious local process or user is replacing the file. This vulnerability affects Thunderbird < 78.10. | |||||
| CVE-2021-29946 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2024-11-21 | 6.8 MEDIUM | 8.8 HIGH |
| Ports that were written as an integer overflow above the bounds of a 16-bit integer could have bypassed port blocking restrictions when used in the Alt-Svc header. This vulnerability affects Firefox ESR < 78.10, Thunderbird < 78.10, and Firefox < 88. | |||||
| CVE-2021-29945 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2024-11-21 | 4.3 MEDIUM | 6.5 MEDIUM |
| The WebAssembly JIT could miscalculate the size of a return type, which could lead to a null read and result in a crash. *Note: This issue only affected x86-32 platforms. Other platforms are unaffected.*. This vulnerability affects Firefox ESR < 78.10, Thunderbird < 78.10, and Firefox < 88. | |||||
| CVE-2021-24002 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2024-11-21 | 6.8 MEDIUM | 8.8 HIGH |
| When a user clicked on an FTP URL containing encoded newline characters (%0A and %0D), the newlines would have been interpreted as such and allowed arbitrary commands to be sent to the FTP server. This vulnerability affects Firefox ESR < 78.10, Thunderbird < 78.10, and Firefox < 88. | |||||
| CVE-2021-23999 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2024-11-21 | 6.8 MEDIUM | 8.8 HIGH |
| If a Blob URL was loaded through some unusual user interaction, it could have been loaded by the System Principal and granted additional privileges that should not be granted to web content. This vulnerability affects Firefox ESR < 78.10, Thunderbird < 78.10, and Firefox < 88. | |||||
| CVE-2021-23998 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2024-11-21 | 4.3 MEDIUM | 6.5 MEDIUM |
| Through complicated navigations with new windows, an HTTP page could have inherited a secure lock icon from an HTTPS page. This vulnerability affects Firefox ESR < 78.10, Thunderbird < 78.10, and Firefox < 88. | |||||
| CVE-2021-23995 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2024-11-21 | 5.1 MEDIUM | 8.8 HIGH |
| When Responsive Design Mode was enabled, it used references to objects that were previously freed. We presume that with enough effort this could have been exploited to run arbitrary code. This vulnerability affects Firefox ESR < 78.10, Thunderbird < 78.10, and Firefox < 88. | |||||
| CVE-2021-23994 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2024-11-21 | 6.8 MEDIUM | 8.8 HIGH |
| A WebGL framebuffer was not initialized early enough, resulting in memory corruption and an out of bound write. This vulnerability affects Firefox ESR < 78.10, Thunderbird < 78.10, and Firefox < 88. | |||||
| CVE-2021-23993 | 1 Mozilla | 1 Thunderbird | 2024-11-21 | 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-2021-23992 | 1 Mozilla | 1 Thunderbird | 2024-11-21 | 4.3 MEDIUM | 4.3 MEDIUM |
| Thunderbird did not check if the user ID associated with an OpenPGP key has a valid self signature. An attacker may create a crafted version of an OpenPGP key, by either replacing the original user ID, or by adding another user ID. If Thunderbird imports and accepts the crafted key, the Thunderbird user may falsely conclude that the false user ID belongs to the correspondent. This vulnerability affects Thunderbird < 78.9.1. | |||||
| CVE-2021-23991 | 1 Mozilla | 1 Thunderbird | 2024-11-21 | 4.0 MEDIUM | 6.8 MEDIUM |
| If a Thunderbird user has previously imported Alice's OpenPGP key, and Alice has extended the validity period of her key, but Alice's updated key has not yet been imported, an attacker may send an email containing a crafted version of Alice's key with an invalid subkey, Thunderbird might subsequently attempt to use the invalid subkey, and will fail to send encrypted email to Alice. This vulnerability affects Thunderbird < 78.9.1. | |||||
| CVE-2021-23987 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2024-11-21 | 6.8 MEDIUM | 8.8 HIGH |
| Mozilla developers and community members reported memory safety bugs present in Firefox 86 and Firefox ESR 78.8. 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 ESR < 78.9, Firefox < 87, and Thunderbird < 78.9. | |||||
| CVE-2021-23984 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2024-11-21 | 4.3 MEDIUM | 6.5 MEDIUM |
| A malicious extension could have opened a popup window lacking an address bar. The title of the popup lacking an address bar should not be fully controllable, but in this situation was. This could have been used to spoof a website and attempt to trick the user into providing credentials. This vulnerability affects Firefox ESR < 78.9, Firefox < 87, and Thunderbird < 78.9. | |||||
| CVE-2021-23982 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2024-11-21 | 4.3 MEDIUM | 6.5 MEDIUM |
| Using techniques that built on the slipstream research, a malicious webpage could have scanned both an internal network's hosts as well as services running on the user's local machine utilizing WebRTC connections. This vulnerability affects Firefox ESR < 78.9, Firefox < 87, and Thunderbird < 78.9. | |||||
| CVE-2021-23981 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2024-11-21 | 5.8 MEDIUM | 8.1 HIGH |
| A texture upload of a Pixel Buffer Object could have confused the WebGL code to skip binding the buffer used to unpack it, resulting in memory corruption and a potentially exploitable information leak or crash. This vulnerability affects Firefox ESR < 78.9, Firefox < 87, and Thunderbird < 78.9. | |||||
| CVE-2021-23978 | 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 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-2021-23973 | 2 Debian, Mozilla | 4 Debian Linux, Firefox, Firefox Esr and 1 more | 2024-11-21 | 4.3 MEDIUM | 6.5 MEDIUM |
| 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. | |||||
