This came as a report to secteam@, but should be tracked in the public bugzilla. > Specifically, we've run FreeBSD inside VMware workstation 9.0.0, captured a > full-memory snapshot (using the ‘snapshot' button in VMware), and resumed the > guest VM multiple times from the same snapshot (using the ‘revert’ button in > VMware). We’ve observed that /dev/random produces repeated outputs each time > the guest is resumed from the same snapshot. In the worst case, we’ve observed > repeated outputs for as long as 100 seconds after resumption. Paper: https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=6956587 admbugs: 499
