Technical details
A vulnerability classified as CWE-789 (Memory Allocation with Excessive Size Value) exists in Samsung's Escargot JavaScript engine. The flaw occurs when the engine processes specific operations—potentially within TypedArray or JSON components—that do not properly validate size parameters before allocating memory. An attacker can exploit this by providing a malicious script that requests an extremely large memory buffer, leading to an 'Excessive Allocation' state. This results in a crash or denial of service (DoS). The attack requires local execution or user interaction (e.g., loading a malicious page/script) and has been addressed in pull request #1565 on the project's GitHub repository.
