CVE-2021-29964 2 Microsoft, Mozilla 4 Windows, Firefox, Firefox Esr and 1 more 2024-11-21 5.8 MEDIUM 7.1 HIGH
A locally-installed hostile program could send `WM_COPYDATA` messages that Firefox would process incorrectly, leading to an out-of-bounds read. *This bug only affects Firefox on Windows. Other operating systems are unaffected.*. This vulnerability affects Thunderbird < 78.11, Firefox < 89, and Firefox ESR < 78.11.
CVE-2021-29963 1 Mozilla 1 Firefox 2024-11-21 4.3 MEDIUM 4.3 MEDIUM
Address bar search suggestions in private browsing mode were re-using session data from normal mode. *This bug only affects Firefox for Android. Other operating systems are unaffected.*. This vulnerability affects Firefox < 89.
CVE-2021-29962 1 Mozilla 1 Firefox 2024-11-21 4.3 MEDIUM 4.3 MEDIUM
Firefox for Android would become unstable and hard-to-recover when a website opened too many popups. *This bug only affects Firefox for Android. Other operating systems are unaffected.*. This vulnerability affects Firefox < 89.
CVE-2021-29961 1 Mozilla 1 Firefox 2024-11-21 4.3 MEDIUM 4.3 MEDIUM
When styling and rendering an oversized `<select>` element, Firefox did not apply correct clipping which allowed an attacker to paint over the user interface. This vulnerability affects Firefox < 89.
CVE-2021-29960 1 Mozilla 1 Firefox 2024-11-21 4.3 MEDIUM 4.3 MEDIUM
Firefox used to cache the last filename used for printing a file. When generating a filename for printing, Firefox usually suggests the web page title. The caching and suggestion techniques combined may have lead to the title of a website visited during private browsing mode being stored on disk. This vulnerability affects Firefox < 89.
CVE-2021-29959 1 Mozilla 1 Firefox 2024-11-21 4.3 MEDIUM 4.3 MEDIUM
When a user has already allowed a website to access microphone and camera, disabling camera sharing would not fully prevent the website from re-enabling it without an additional prompt. This was only possible if the website kept recording with the microphone until re-enabling the camera. This vulnerability affects Firefox < 89.
CVE-2021-29958 1 Mozilla 1 Firefox 2024-11-21 4.3 MEDIUM 4.3 MEDIUM
When a download was initiated, the client did not check whether it was in normal or private browsing mode, which led to private mode cookies being shared in normal browsing mode. This vulnerability affects Firefox for iOS < 34.
CVE-2021-29957 1 Mozilla 1 Thunderbird 2024-11-21 4.3 MEDIUM 4.3 MEDIUM
If a MIME encoded email contains an OpenPGP inline signed or encrypted message part, but also contains an additional unprotected part, Thunderbird did not indicate that only parts of the message are protected. This vulnerability affects Thunderbird < 78.10.2.
CVE-2021-29956 1 Mozilla 1 Thunderbird 2024-11-21 4.3 MEDIUM 4.3 MEDIUM
OpenPGP secret keys that were imported using Thunderbird version 78.8.1 up to version 78.10.1 were stored unencrypted on the user's local disk. The master password protection was inactive for those keys. Version 78.10.2 will restore the protection mechanism for newly imported keys, and will automatically protect keys that had been imported using affected Thunderbird versions. This vulnerability affects Thunderbird < 78.10.2.
CVE-2021-29955 1 Mozilla 2 Firefox, Firefox Esr 2024-11-21 2.6 LOW 5.3 MEDIUM
A transient execution vulnerability, named Floating Point Value Injection (FPVI) allowed an attacker to leak arbitrary memory addresses and may have also enabled JIT type confusion attacks. (A related vulnerability, Speculative Code Store Bypass (SCSB), did not affect Firefox.). This vulnerability affects Firefox ESR < 78.9 and Firefox < 87.
CVE-2021-29954 1 Mozilla 1 Hubs Cloud Reticulum 2024-11-21 5.0 MEDIUM 9.8 CRITICAL
Proxy functionality built into Hubs Cloud’s Reticulum software allowed access to internal URLs, including the metadata service. This vulnerability affects Hubs Cloud < mozillareality/reticulum/1.0.1/20210428201255.
CVE-2021-29953 1 Mozilla 1 Firefox 2024-11-21 4.3 MEDIUM 6.1 MEDIUM
A malicious webpage could have forced a Firefox for Android user into executing attacker-controlled JavaScript in the context of another domain, resulting in a Universal Cross-Site Scripting vulnerability. *Note: This issue only affected Firefox for Android. Other operating systems are unaffected. Further details are being temporarily withheld to allow users an opportunity to update.*. This vulnerability affects Firefox < 88.0.1 and Firefox for Android < 88.1.3.
CVE-2021-29952 1 Mozilla 1 Firefox 2024-11-21 5.1 MEDIUM 7.5 HIGH
When Web Render components were destructed, a race condition could have caused undefined behavior, and we presume that with enough effort may have been exploitable to run arbitrary code. This vulnerability affects Firefox < 88.0.1 and Firefox for Android < 88.1.3.
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-2021-29947 1 Mozilla 1 Firefox 2024-11-21 6.8 MEDIUM 8.8 HIGH
Mozilla developers and community members reported memory safety bugs present in Firefox 87. 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 < 88.
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.
