CVE-2023-41268Network attack vector

Service crash via stale execution stack limit

Published Dec 6, 2023 · Updated Dec 2, 2024

Improper input validation in Samsung Escargot 3.0.0 through 4.0.0 allows remote attackers to crash the engine with crafted JavaScript. During top-level await processing with a class-variable initializer, ExecutionPauser resumes an ExecutionState without refreshing its native stack limit, allowing recursion to exhaust the stack. Unauthenticated network delivery is sufficient when an embedding application evaluates attacker-controlled script, and the documented consequence is a segmentation fault and service interruption.
