Fixed In Version:	nodejs-node-uuid 1.4.4
Doc Type:	Bug Fix
Doc Text:	It was found that NodeJS node-uuid used Math.random() to create a GUID (Globally Unique Identifier) which does not provide enough entropy (on some platforms it only provides 32 bits) which can result in collisions of GUIDs. An attacker could use this to guess GUID values and leverage further attacks against a system using node-uuid.

Description Andrej Nemec 2016-04-14 03:53:03 EDT

node-uuid prior to 1.4.4 contained a bug that caused it to consistently
fall back to using Math.random() instead of a more cryptographically sound
source of entropy, the native crypto module.
