Technical details

An out-of-bounds read vulnerability (CWE-125) exists in Samsung's Escargot JavaScript engine. The flaw is located within the engine's handling of memory buffers, where insufficient bounds checking allows a read operation to exceed the intended buffer limits. A remote attacker can exploit this by providing specially crafted JavaScript code that triggers the out-of-bounds access. Successful exploitation can lead to the exposure of sensitive memory contents (resource leak) or a partial denial of service. The vulnerability was addressed in pull request #1554 on the Escargot GitHub repository.
