Description

Note: It apperared that an attacker would have to be able to open and aceess /dev/sg* which in RHEL systems are by default allowed to a privileged user (real non-container root) and members of the "disk" group (empty by default). Therefore we assume this issue is a bug and not a security flaw. |
