Executive brief
Samsung Escargot, an open-source JavaScript engine, contains a vulnerability that can cause the application to crash. This occurs when the engine attempts to process certain complex code sequences, such as nested error handling. An exploit could lead to a denial-of-service, impacting the reliability of devices or applications using this engine.
Technical details
A vulnerability classified as CWE-763 (Release of Invalid Pointer or Reference) exists in Samsung's Escargot JavaScript engine. The flaw is rooted in the handling of edge cases, such as nested 'eval' calls with 'finally' blocks, where the engine may attempt to dereference a null or invalid pointer when processing error values. Specifically, in 'src/api/EscargotPublic.cpp', the code may call 'toStringWithoutException' on a null pointer returned by 'error.value()'. A local attacker could exploit this by providing specially crafted JavaScript code that triggers these edge cases, leading to a crash (Denial of Service). The issue was addressed in pull request #1565.
