CVE-2024-4772 1 Mozilla 1 Firefox 2026-06-17 N/A 5.9 MEDIUM
An HTTP digest authentication nonce value was generated using `rand()` which could lead to predictable values. This vulnerability affects Firefox < 126.
CVE-2024-4771 1 Mozilla 1 Firefox 2026-06-17 N/A 8.6 HIGH
A memory allocation check was missing which would lead to a use-after-free if the allocation failed. This could have triggered a crash or potentially be leveraged to achieve code execution. This vulnerability affects Firefox < 126.
CVE-2024-4770 1 Mozilla 2 Firefox, Thunderbird 2026-06-17 N/A 8.8 HIGH
When saving a page to PDF, certain font styles could have led to a potential use-after-free crash. This vulnerability affects Firefox < 126, Firefox ESR < 115.11, and Thunderbird < 115.11.
CVE-2024-4769 2 Debian, Mozilla 3 Debian Linux, Firefox, Thunderbird 2026-06-17 N/A 5.9 MEDIUM
When importing resources using Web Workers, error messages would distinguish the difference between `application/javascript` responses and non-script responses. This could have been abused to learn information cross-origin. This vulnerability affects Firefox < 126, Firefox ESR < 115.11, and Thunderbird < 115.11.
CVE-2024-4768 2 Debian, Mozilla 3 Debian Linux, Firefox, Thunderbird 2026-06-17 N/A 6.1 MEDIUM
A bug in popup notifications' interaction with WebAuthn made it easier for an attacker to trick a user into granting permissions. This vulnerability affects Firefox < 126, Firefox ESR < 115.11, and Thunderbird < 115.11.
CVE-2024-4767 2 Debian, Mozilla 3 Debian Linux, Firefox, Thunderbird 2026-06-17 N/A 4.3 MEDIUM
If the `browser.privatebrowsing.autostart` preference is enabled, IndexedDB files were not properly deleted when the window was closed. This preference is disabled by default in Firefox. This vulnerability affects Firefox < 126, Firefox ESR < 115.11, and Thunderbird < 115.11.
CVE-2024-4766 2 Google, Mozilla 2 Android, Firefox 2026-06-17 N/A 4.3 MEDIUM
Different techniques existed to obscure the fullscreen notification in Firefox for Android. These could have led to potential user confusion and spoofing attacks. *This bug only affects Firefox for Android. Other versions of Firefox are unaffected.* This vulnerability affects Firefox < 126.
CVE-2024-4765 1 Mozilla 1 Firefox 2026-06-17 N/A 8.1 HIGH
Web application manifests were stored by using an insecure MD5 hash which allowed for a hash collision to overwrite another application's manifest. This could have been exploited to run arbitrary code in another application's context. *This issue only affects Firefox for Android. Other versions of Firefox are unaffected.* This vulnerability affects Firefox < 126.
CVE-2024-4764 1 Mozilla 1 Firefox 2026-06-17 N/A 9.8 CRITICAL
Multiple WebRTC threads could have claimed a newly connected audio input leading to use-after-free. This vulnerability affects Firefox < 126.
CVE-2024-4367 3 Debian, Mozilla, Open-xchange 4 Debian Linux, Firefox, Thunderbird and 1 more 2026-06-17 N/A 8.8 HIGH
A type check was missing when handling fonts in PDF.js, which would allow arbitrary JavaScript execution in the PDF.js context. This vulnerability affects Firefox < 126, Firefox ESR < 115.11, and Thunderbird < 115.11.
CVE-2024-3865 1 Mozilla 1 Firefox 2026-06-17 N/A 8.1 HIGH
Memory safety bugs present in Firefox 124. 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 < 125.
CVE-2024-3864 2 Debian, Mozilla 3 Debian Linux, Firefox, Thunderbird 2026-06-17 N/A 8.1 HIGH
Memory safety bug present in Firefox 124, Firefox ESR 115.9, and Thunderbird 115.9. This bug showed evidence of memory corruption and we presume that with enough effort this could have been exploited to run arbitrary code. This vulnerability affects Firefox < 125, Firefox ESR < 115.10, and Thunderbird < 115.10.
CVE-2024-3863 1 Mozilla 2 Firefox, Thunderbird 2026-06-17 N/A 9.8 CRITICAL
The executable file warning was not presented when downloading .xrm-ms files. *Note: This issue only affected Windows operating systems. Other operating systems are unaffected.* This vulnerability affects Firefox < 125, Firefox ESR < 115.10, and Thunderbird < 115.10.
CVE-2024-3862 1 Mozilla 1 Firefox 2026-06-17 N/A 5.3 MEDIUM
The MarkStack assignment operator, part of the JavaScript engine, could access uninitialized memory if it were used in a self-assignment. This vulnerability affects Firefox < 125.
CVE-2024-3861 2 Debian, Mozilla 3 Debian Linux, Firefox, Thunderbird 2026-06-17 N/A 4.0 MEDIUM
If an AlignedBuffer were assigned to itself, the subsequent self-move could result in an incorrect reference count and later use-after-free. This vulnerability affects Firefox < 125, Firefox ESR < 115.10, and Thunderbird < 115.10.
CVE-2024-3860 1 Mozilla 1 Firefox 2026-06-17 N/A 6.2 MEDIUM
An out-of-memory condition during object initialization could result in an empty shape list. If the JIT subsequently traced the object it would crash. This vulnerability affects Firefox < 125.
CVE-2024-3859 2 Debian, Mozilla 3 Debian Linux, Firefox, Thunderbird 2026-06-17 N/A 5.9 MEDIUM
On 32-bit versions there were integer-overflows that led to an out-of-bounds-read that potentially could be triggered by a malformed OpenType font. This vulnerability affects Firefox < 125, Firefox ESR < 115.10, and Thunderbird < 115.10.
CVE-2024-3858 1 Mozilla 1 Firefox 2026-06-17 N/A 7.5 HIGH
It was possible to mutate a JavaScript object so that the JIT could crash while tracing it. This vulnerability affects Firefox < 125.
CVE-2024-3857 2 Debian, Mozilla 3 Debian Linux, Firefox, Thunderbird 2026-06-17 N/A 7.8 HIGH
The JIT created incorrect code for arguments in certain cases. This led to potential use-after-free crashes during garbage collection. This vulnerability affects Firefox < 125, Firefox ESR < 115.10, and Thunderbird < 115.10.
CVE-2024-3856 1 Mozilla 1 Firefox 2026-06-17 N/A 8.8 HIGH
