Executive brief
Samsung Escargot, an open-source JavaScript engine, is vulnerable to a crash when processing specifically crafted, deeply nested data. An attacker could provide a malicious file or payload that causes the application to stop responding or shut down unexpectedly. This primarily impacts the availability of services or devices using this engine, such as smart TVs or appliances.
Technical details
An uncontrolled recursion vulnerability (CWE-674) exists in the Samsung Escargot JavaScript engine. The flaw is triggered when the engine processes oversized serialized data payloads, specifically within components like JSON parsing or typed array handling. An attacker can exploit this by providing deeply nested or malformed data that exhausts the stack, leading to a crash. The vulnerability was addressed in pull request #1565, which includes fixes for null pointer dereferences and recursion depth issues in components such as BuiltinTypedArray.cpp and JSON.cpp. Exploitation requires the victim to process a malicious payload (User Interaction required).
