Last modified

CVE-2011-3009 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 2.09% chance of exploitation in the next 30 days.
