|---|---|---|---|---|
| CVE-2021-29971 | 1 Mozilla | 1 Firefox | 2024-08-03 | 9.8 Critical |
| If a user had granted a permission to a webpage and saved that grant, any webpage running on the same host - irrespective of scheme or port - would be granted that permission. *This bug only affects Firefox for Android. Other operating systems are unaffected.*. This vulnerability affects Firefox < 90. | ||||
| CVE-2021-29975 | 1 Mozilla | 1 Firefox | 2024-08-03 | 6.5 Medium |
| Through a series of DOM manipulations, a message, over which the attacker had control of the text but not HTML or formatting, could be overlaid on top of another domain (with the new domain correctly shown in the address bar) resulting in possible user confusion. This vulnerability affects Firefox < 90. | ||||
| CVE-2021-29972 | 1 Mozilla | 1 Firefox | 2024-08-03 | 8.8 High |
| A use-after-free vulnerability was found via testing, and traced to an out-of-date Cairo library. Updating the library resolved the issue, and may have remediated other, unknown security vulnerabilities as well. This vulnerability affects Firefox < 90. | ||||
| CVE-2021-29977 | 1 Mozilla | 1 Firefox | 2024-08-03 | 8.8 High |
| Mozilla developers reported memory safety bugs present in Firefox 89. 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 < 90. | ||||
| CVE-2021-29964 | 2 Microsoft, Mozilla | 4 Windows, Firefox, Firefox Esr and 1 more | 2024-08-03 | 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-2021-29965 | 1 Mozilla | 1 Firefox | 2024-08-03 | 5.3 Medium |
| A malicious website that causes an HTTP Authentication dialog to be spawned could trick the built-in password manager to suggest passwords for the currently active website instead of the website that triggered the dialog. *This bug only affects Firefox for Android. Other operating systems are unaffected.*. This vulnerability affects Firefox < 89. | ||||
| CVE-2021-29966 | 1 Mozilla | 1 Firefox | 2024-08-03 | 8.8 High |
| Mozilla developers reported memory safety bugs present in Firefox 88. 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 < 89. | ||||
| CVE-2021-29963 | 1 Mozilla | 1 Firefox | 2024-08-03 | 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-2021-29946 | 2 Mozilla, Redhat | 5 Firefox, Firefox Esr, Thunderbird and 2 more | 2024-08-03 | 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-2021-29953 | 1 Mozilla | 1 Firefox | 2024-08-03 | 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-2021-29945 | 2 Mozilla, Redhat | 5 Firefox, Firefox Esr, Thunderbird and 2 more | 2024-08-03 | 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-2021-29952 | 1 Mozilla | 1 Firefox | 2024-08-03 | 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-2021-29961 | 1 Mozilla | 1 Firefox | 2024-08-03 | 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-2021-29951 | 2 Microsoft, Mozilla | 4 Windows, Firefox, Firefox Esr and 1 more | 2024-08-03 | 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-2021-29944 | 1 Mozilla | 1 Firefox | 2024-08-03 | 6.1 Medium |
| Lack of escaping allowed HTML injection when a webpage was viewed in Reader View. While a Content Security Policy prevents direct code execution, HTML injection is still possible. *Note: This issue only affected Firefox for Android. Other operating systems are unaffected.*. This vulnerability affects Firefox < 88. | ||||
| CVE-2021-29960 | 1 Mozilla | 1 Firefox | 2024-08-03 | 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-2021-29955 | 1 Mozilla | 2 Firefox, Firefox Esr | 2024-08-03 | 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-2021-29962 | 1 Mozilla | 1 Firefox | 2024-08-03 | 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-2021-29959 | 1 Mozilla | 1 Firefox | 2024-08-03 | 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-2021-29947 | 1 Mozilla | 1 Firefox | 2024-08-03 | 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. | ||||
