FKIE_CVE-2011-3009

Vulnerability from fkie_nvd - Published: 2011-08-05 22:55 - Updated: 2026-06-16 23:32
Severity
Summary
Ruby before 1.8.6-p114 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, a related issue to CVE-2003-0900.
