Description

The backend for XenSource Xen Para Virtualized Frame Buffer (PVFB) in Xen ioemu does not properly restrict the frame buffer size, which allows attackers to cause a denial of service (crash) by mapping an arbitrary amount of guest memory.

Solution(s)

  • redhat-upgrade-xen
  • redhat-upgrade-xen-devel
  • redhat-upgrade-xen-libs

With Rapid7 live dashboards, I have a clear view of all the assets on my network, which ones can be exploited, and what I need to do in order to reduce the risk in my environment in real-time. No other tool gives us that kind of value and insight.
