Details

Stack overflow in rustc_serialize when parsing deeply nested JSON When parsing JSON using `json::Json::from_str`, there is no limit to the depth of the stack, therefore deeply nested objects can cause a stack overflow, which aborts the process. Example code that triggers the vulnerability is ```rust fn main() { let _ = rustc_serialize::json::Json::from_str(&"[0,[".repeat(10000)); } ``` [serde](https://crates.io/crates/serde) is recommended as a replacement to rustc_serialize.
