Buffer overflow in the backend of XenSource Xen Para Virtualized Frame Buffer (PVFB) 3.0 through 3.1.2 allows local users to cause a denial of service (crash) and possibly execute arbitrary code via a crafted description of a shared framebuffer.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
