| CVE-2021-30547 | 5 Debian, Fedoraproject, Google and 2 more | 6 Debian Linux, Fedora, Chrome and 3 more | 2024-08-03 | 8.8 High |
| Out of bounds write in ANGLE in Google Chrome prior to 91.0.4472.101 allowed a remote attacker to potentially perform out of bounds memory access via a crafted HTML page. | ||||
| CVE-2021-29991 | 1 Mozilla | 2 Firefox, Thunderbird | 2024-08-03 | 8.1 High |
| Firefox incorrectly accepted a newline in a HTTP/3 header, interpretting it as two separate headers. This allowed for a header splitting attack against servers using HTTP/3. This vulnerability affects Firefox < 91.0.1 and Thunderbird < 91.0.1. | ||||

| Firefox incorrectly treated an inline list-item element as a block element, resulting in an out of bounds read or memory corruption, and a potentially exploitable crash. This vulnerability affects Thunderbird < 78.13, Thunderbird < 91, Firefox ESR < 78.13, and Firefox < 91. | ||||
| CVE-2021-29990 | 1 Mozilla | 1 Firefox | 2024-08-03 | 8.8 High |
| Mozilla developers and community members reported memory safety bugs present in Firefox 90. 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 < 91. | ||||
| CVE-2021-29984 | 2 Mozilla, Redhat | 5 Firefox, Firefox Esr, Thunderbird and 2 more | 2024-08-03 | 8.8 High |
| Instruction reordering resulted in a sequence of instructions that would cause an object to be incorrectly considered during garbage collection. This led to memory corruption and a potentially exploitable crash. This vulnerability affects Thunderbird < 78.13, Thunderbird < 91, Firefox ESR < 78.13, and Firefox < 91. | ||||
| CVE-2021-29993 | 1 Mozilla | 1 Firefox | 2024-08-03 | 8.1 High |
| Firefox for Android allowed navigations through the `intent://` protocol, which could be used to cause crashes and UI spoofs. *This bug only affects Firefox for Android. Other operating systems are unaffected.*. This vulnerability affects Firefox < 92. | ||||
| CVE-2021-29989 | 2 Mozilla, Redhat | 5 Firefox, Firefox Esr, Thunderbird and 2 more | 2024-08-03 | 8.8 High |
| Mozilla developers reported memory safety bugs present in Firefox 90 and Firefox ESR 78.12. 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 < 78.13, Firefox ESR < 78.13, and Firefox < 91. | ||||
| CVE-2021-29985 | 2 Mozilla, Redhat | 5 Firefox, Firefox Esr, Thunderbird and 2 more | 2024-08-03 | 8.8 High |
| A use-after-free vulnerability in media channels could have led to memory corruption and a potentially exploitable crash. This vulnerability affects Thunderbird < 78.13, Thunderbird < 91, Firefox ESR < 78.13, and Firefox < 91. | ||||
| CVE-2021-29983 | 2 Google, Mozilla | 2 Android, Firefox | 2024-08-03 | 6.5 Medium |
| Firefox for Android could get stuck in fullscreen mode and not exit it even after normal interactions that should cause it to exit. *Note: This issue only affected Firefox for Android. Other operating systems are unaffected.*. This vulnerability affects Firefox < 91. | ||||
| CVE-2021-29987 | 2 Linux, Mozilla | 3 Linux Kernel, Firefox, Thunderbird | 2024-08-03 | 6.5 Medium |
| After requesting multiple permissions, and closing the first permission panel, subsequent permission panels will be displayed in a different position but still record a click in the default location, making it possible to trick a user into accepting a permission they did not want to. *This bug only affects Firefox on Linux. Other operating systems are unaffected.*. This vulnerability affects Firefox < 91 and Thunderbird < 91. | ||||
| CVE-2021-29982 | 1 Mozilla | 2 Firefox, Thunderbird | 2024-08-03 | 6.5 Medium |
| Due to incorrect JIT optimization, we incorrectly interpreted data from the wrong type of object, resulting in the potential leak of a single bit of memory. This vulnerability affects Firefox < 91 and Thunderbird < 91. | ||||
| CVE-2021-29981 | 1 Mozilla | 2 Firefox, Thunderbird | 2024-08-03 | 8.8 High |
| An issue present in lowering/register allocation could have led to obscure but deterministic register confusion failures in JITted code that would lead to a potentially exploitable crash. This vulnerability affects Firefox < 91 and Thunderbird < 91. | ||||
| CVE-2021-29980 | 2 Mozilla, Redhat | 5 Firefox, Firefox Esr, Thunderbird and 2 more | 2024-08-03 | 8.8 High |
| Uninitialized memory in a canvas object could have caused an incorrect free() leading to memory corruption and a potentially exploitable crash. This vulnerability affects Thunderbird < 78.13, Thunderbird < 91, Firefox ESR < 78.13, and Firefox < 91. | ||||
| CVE-2021-29970 | 2 Mozilla, Redhat | 5 Firefox, Firefox Esr, Thunderbird and 2 more | 2024-08-03 | 8.8 High |
| A malicious webpage could have triggered a use-after-free, memory corruption, and a potentially exploitable crash. *This bug could only be triggered when accessibility was enabled.*. This vulnerability affects Thunderbird < 78.12, Firefox ESR < 78.12, and Firefox < 90. | ||||
| CVE-2021-29967 | 2 Mozilla, Redhat | 5 Firefox, Firefox Esr, Thunderbird and 2 more | 2024-08-03 | 8.8 High |
| Mozilla developers reported memory safety bugs present in Firefox 88 and Firefox ESR 78.11. 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 < 78.11, Firefox < 89, and Firefox ESR < 78.11. | ||||
| CVE-2021-29974 | 1 Mozilla | 1 Firefox | 2024-08-03 | 4.3 Medium |
| When network partitioning was enabled, e.g. as a result of Enhanced Tracking Protection settings, a TLS error page would allow the user to override an error on a domain which had specified HTTP Strict Transport Security (which implies that the error should not be override-able.) This issue did not affect the network connections, and they were correctly upgraded to HTTPS automatically. This vulnerability affects Firefox < 90. | ||||
| CVE-2021-29973 | 1 Mozilla | 1 Firefox | 2024-08-03 | 8.8 High |
| Password autofill was enabled without user interaction on insecure websites on Firefox for Android. This was corrected to require user interaction with the page before a user's password would be entered by the browser's autofill functionality *This bug only affects Firefox for Android. Other operating systems are unaffected.*. This vulnerability affects Firefox < 90. | ||||
| CVE-2021-29986 | 3 Linux, Mozilla, Redhat | 6 Linux Kernel, Firefox, Firefox Esr and 3 more | 2024-08-03 | 8.1 High |
| A suspected race condition when calling getaddrinfo led to memory corruption and a potentially exploitable crash. *Note: This issue only affected Linux operating systems. Other operating systems are unaffected.* This vulnerability affects Thunderbird < 78.13, Thunderbird < 91, Firefox ESR < 78.13, and Firefox < 91. | ||||
| CVE-2021-29968 | 2 Microsoft, Mozilla | 2 Windows, Firefox | 2024-08-03 | 8.1 High |

| CVE-2021-29976 | 2 Mozilla, Redhat | 5 Firefox, Firefox Esr, Thunderbird and 2 more | 2024-08-03 | 8.8 High |
| Mozilla developers reported memory safety bugs present in code shared between Firefox and Thunderbird. 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 < 78.12, Firefox ESR < 78.12, and Firefox < 90. | ||||
