Buffer overflow in Node.js - CVE-2014-5256

Vulnerability details

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

Node.js 0.8 before 0.8.28 and 0.10 before 0.10.30 does not consider the possibility of recursive processing that triggers V8 garbage collection in conjunction with a V8 interrupt, which allows remote attackers to cause a denial of service (memory corruption and application crash) via deep JSON objects whose parsing lets this interrupt mask an overflow of the program stack.
