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
A use-after-free could occur during WASM execution if garbage collection ran during the creation of an array. This vulnerability affects Firefox < 125.
CVE-2024-3855 1 Mozilla 1 Firefox 2026-06-17 N/A 6.5 MEDIUM
In certain cases the JIT incorrectly optimized MSubstr operations, which led to out-of-bounds reads. This vulnerability affects Firefox < 125.
CVE-2024-3854 1 Mozilla 2 Firefox, Thunderbird 2026-06-17 N/A 8.8 HIGH
In some code patterns the JIT incorrectly optimized switch statements and generated code with out-of-bounds-reads. This vulnerability affects Firefox < 125, Firefox ESR < 115.10, and Thunderbird < 115.10.
CVE-2024-3853 1 Mozilla 1 Firefox 2026-06-17 N/A 7.5 HIGH
A use-after-free could result if a JavaScript realm was in the process of being initialized when a garbage collection started. This vulnerability affects Firefox < 125.
CVE-2024-3852 1 Mozilla 2 Firefox, Thunderbird 2026-06-17 N/A 7.5 HIGH
GetBoundName could return the wrong version of an object when JIT optimizations were applied. This vulnerability affects Firefox < 125, Firefox ESR < 115.10, and Thunderbird < 115.10.
CVE-2024-3302 1 Mozilla 2 Firefox, Thunderbird 2026-06-17 N/A 3.7 LOW
There was no limit to the number of HTTP/2 CONTINUATION frames that would be processed. A server could abuse this to create an Out of Memory condition in the browser. This vulnerability affects Firefox < 125, Firefox ESR < 115.10, and Thunderbird < 115.10.
CVE-2024-31393 2 Apple, Mozilla 2 Iphone Os, Firefox 2026-06-17 N/A 4.3 MEDIUM
Dragging Javascript URLs to the address bar could cause them to be loaded, bypassing restrictions and security protections This vulnerability affects Firefox for iOS < 124.
CVE-2024-31392 2 Apple, Mozilla 2 Iphone Os, Firefox 2026-06-17 N/A 7.5 HIGH
If an insecure element was added to a page after a delay, Firefox would not replace the secure icon with a mixed content security status This vulnerability affects Firefox for iOS < 124.
CVE-2024-2616 1 Mozilla 2 Firefox, Thunderbird 2026-06-17 N/A 2.7 LOW
To harden ICU against exploitation, the behavior for out-of-memory conditions was changed to crash instead of attempt to continue. This vulnerability affects Firefox ESR < 115.9 and Thunderbird < 115.9.
CVE-2024-2615 1 Mozilla 1 Firefox 2026-06-17 N/A 9.8 CRITICAL
Memory safety bugs present in Firefox 123. 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 < 124.
CVE-2024-2614 2 Debian, Mozilla 3 Debian Linux, Firefox, Thunderbird 2026-06-17 N/A 8.8 HIGH
Memory safety bugs present in Firefox 123, Firefox ESR 115.8, and Thunderbird 115.8. 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 < 124, Firefox ESR < 115.9, and Thunderbird < 115.9.
CVE-2024-2613 1 Mozilla 1 Firefox 2026-06-17 N/A 7.5 HIGH
Data was not properly sanitized when decoding a QUIC ACK frame; this could have led to unrestricted memory consumption and a crash. This vulnerability affects Firefox < 124.
