The following CVEs affect all products:

CVE-2024-2609 (Only Thunderbird and FireFox ESR):

The permission prompt input delay could expire while the window is not in focus. This makes it vulnerable to clickjacking by malicious websites.


CVE-2024-3302:

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.


CVE-2024-3852:

GetBoundName could return the wrong version of an object when JIT optimizations were applied.


CVE-2024-3854:

In some code patterns the JIT incorrectly optimized switch statements and generated code with out-of-bounds-reads.


CVE-2024-3857:

The JIT created incorrect code for arguments in certain cases. This led to potential use-after-free crashes during garbage collection.


CVE-2024-3859:

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.


CVE-2024-3861:

If an AlignedBuffer were assigned to itself, the subsequent self-move could result in an incorrect reference count and later use-after-free.


CVE-2024-3864:

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.
