A vulnerability classified as problematic was found in Node.js up to 0.8.27/0.10.29 (JavaScript Library). This vulnerability affects an unknown code of the component V8 Handler. The manipulation with an unknown input leads to a memory corruption vulnerability. The CWE definition for the vulnerability is CWE-119. As an impact it is known to affect availability.

The weakness was released 07/31/2014 as V8 Memory Corruption and Stack Overflow (fixed in Node v0.8.28 and v0.10.30) as confirmed blog post (Website). The advisory is shared for download at blog.nodejs.org. This vulnerability was named CVE-2014-5256 since 08/15/2014. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. There are neither technical details nor an exploit publicly available.

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 SecurityFocus (BID 69157), Secunia (SA56216), SecurityTracker (ID 1030811), Vulnerability Center (SBV-47625) and Tenable (82395).
