Interpreter abort via oversized buffer allocation

Resource exhaustion in JerryScript 3.0 allows context-dependent attackers to abort the interpreter with crafted JavaScript. SharedArrayBuffer.prototype.slice and typed-array construction accept attacker-controlled 2 GiB buffer sizes, pass them through ecma_arraybuffer_allocate_buffer to jmem_heap_alloc, and invoke malloc without an effective allocation limit. Local execution of the crafted script is required; the demonstrated result is an out-of-memory abort that interrupts interpreter availability, with no reported data disclosure or modification.
