PRIOn knowledge basePRION:CVE-2014-8867Design/Logic Flaw
The acceleration support for the “REP MOVS” instruction in Xen 4.4.x, 3.2.x, and earlier lacks properly bounds checking for memory mapped I/O (MMIO) emulated in the hypervisor, which allows local HVM guests to cause a denial of service (host crash) via unspecified vectors.
