Red Hat Product Errata RHSA-2012:1506 0 normal SHIPPED_LIVE Important: Red Hat Enterprise Virtualization Manager 3.1 2012-12-04 23:58:40 UTC

Description David Jorm 2011-11-18 01:43:18 UTC
It was found that under certain conditions, SPICE would fail to lock the screen on a virtual machine between sessions. A user with access to a virtual machine in the Red Hat Enterprise Virtualization Manager could exploit this flaw to gain access to another user's unlocked desktop session. This is a security concern in environments where multiple users have access to the same virtual machine, but they use different operating system credentials to log on to that virtual machine.
