CVE-2015-8851
Description
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.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
