CVE-2011-2686
Estado: ModificadaMedia (5)—
Ruby before 1.8.7-p352 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. NOTE: this issue exists because of a regression during Ruby 1.8.6 development.
CVSS
- Versión: 2.0
- Vector: AV:N/AC:L/Au:N/C:P/I:N/A:N
