Test ID:	1.3.6.1.4.1.25623.1.0.902558
Category:	Denial of Service
Title:	Ruby Random Number Generation Local Denial Of Service Vulnerability
Summary:	Ruby is prone to local denial of service vulnerability.
Description:	Summary: Ruby is prone to local denial of service vulnerability. Vulnerability Insight: The flaw exists because ruby does not reset the random seed upon forking, which makes it easier for context-dependent attackers to predict the values of random numbers by leveraging knowledge of the number sequence obtained in a different child process. Vulnerability Impact: Successful exploits may allow local attackers to cause denial-of-service conditions. Affected Software/OS: Ruby Versions prior to 1.8.7-p352. Solution: Upgrade to Ruby version 1.8.7-p352 or later. CVSS Score: 5.0 CVSS Vector: AV:N/AC:L/Au:N/C:P/I:N/A:N
