Vulnerability Descriptions: - CVE-2024-7652: An error in the ECMA-262 specification relating to Async Generators could have resulted in a type confusion, potentially leading to memory corruption and an exploitable crash. - CVE-2024-6600: Due to large allocation checks in Angle for GLSL shaders being too lenient, an out-of-bounds access could occur when allocating more than 8192 ints in private shader memory on macOS. - 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 led 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, 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. 4.
