The vulnerability scanner Nessus provides a plugin with the ID 82395 (Mandriva Linux Security Advisory : nodejs (MDVSA-2015:142)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Mandriva Local Security Checks.

Applying a patch is able to eliminate this problem. The blog post contains the following remark:

To mitigate against deep JSON parsing you can limit the size of the string you parse against, or ban clients who trigger a RangeError for parsing JSON. There is no specific maximum size of a JSON string, though keeping the max to the size of your known message bodies is suggested. If your message bodies cannot be over 20K, there's no reason to accept 1MB bodies. For web frameworks that do automatic JSON parsing, you may need to configure the routes that accept JSON payloads to have a maximum body size.

The vulnerability is also documented in the databases at Tenable (82395), SecurityFocus (BID 69157†), Secunia (SA56216†), SecurityTracker (ID 1030811†) and Vulnerability Center (SBV-47625†).
