Description Christopher Fore 2024-07-17 12:47:48 UTC

The following CVEs affect all four Mozilla products in-tree (Firefox, Firefox ESR, Thunderbird, and Spidermonkey):


CVE-2024-6601:

A race condition could lead to a cross-origin container obtaining permissions of the top-level origin.


CVE-2024-6602:

A mismatch between allocator and deallocator could have lead to memory corruption.


CVE-2024-6603:

In an out-of-memory scenario an allocation could fail but free would have been called on the pointer afterwards leading to memory corruption.


CVE-2024-6604:

Memory safety bugs present in Firefox 127, Firefox ESR 115.12, Thunderbird 127, and Thunderbird 115.12. 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.



Please refer to the blocking bugs for the package-specific CVEs.
