A nested iframe, triggering a cross-site navigation, could send SameSite=Strict or Lax cookies. This vulnerability affects Firefox < 128 and Thunderbird < 128.

It was possible to move the cursor using pointerlock from an iframe. This allowed moving the cursor outside of the viewport and the Firefox window. This vulnerability affects Firefox < 128 and Thunderbird < 128.

A mismatch between allocator and deallocator could have led to memory corruption. This vulnerability affects Firefox < 128, Firefox ESR < 115.13, Thunderbird < 115.13, and Thunderbird < 128.

The frame iterator could get stuck in a loop when encountering certain wasm frames leading to incorrect stack traces. This vulnerability affects Firefox < 128 and Thunderbird < 128.

Clipboard code failed to check the index on an array access. This could have led to an out-of-bounds read. This vulnerability affects Firefox < 128 and Thunderbird < 128.

In an out-of-memory scenario an allocation could fail but free would have been called on the pointer afterwards leading to memory corruption. This vulnerability affects Firefox < 128, Firefox ESR < 115.13, Thunderbird < 115.13, and Thunderbird < 128.

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. This vulnerability affects Firefox < 128, Firefox ESR < 115.13, Thunderbird < 115.13, and Thunderbird < 128.

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 mac OS. This vulnerability affects Firefox < 128, Firefox ESR < 115.13, Thunderbird < 115.13, and Thunderbird < 128.
