  "details" : [ "Forge (also called `node-forge`) is a native implementation of Transport Layer Security in JavaScript. Prior to version 1.4.0, a Denial of Service (DoS) vulnerability exists in the node-forge library due to an infinite loop in the BigInteger.modInverse() function (inherited from the bundled jsbn library). When modInverse() is called with a zero value as input, the internal Extended Euclidean Algorithm enters an unreachable exit condition, causing the process to hang indefinitely and consume 100% CPU. Version 1.4.0 patches the issue.", "A flaw was found in the node-forge library, a JavaScript implementation of Transport Layer Security. This vulnerability, inherited from the bundled jsbn library, allows a remote attacker to cause a Denial of Service (DoS). When the BigInteger.modInverse() function is called with a zero value, it enters an infinite loop, causing the process to hang indefinitely and consume 100% of the CPU resources." ],
