Description: This update for xen fixes several issues. These security issues were fixed: - CVE-2016-7092: The get_page_from_l3e function in arch/x86/mm.c in Xen allowed local 32-bit PV guest OS administrators to gain host OS privileges via vectors related to L3 recursive pagetables (bsc#995785) - CVE-2016-7093: Xen allowed local HVM guest OS administrators to overwrite hypervisor memory and consequently gain host OS privileges by leveraging mishandling of instruction pointer truncation during emulation (bsc#995789) - CVE-2016-7094: Buffer overflow in Xen allowed local x86 HVM guest OS administrators on guests running with shadow paging to cause a denial of service via a pagetable update (bsc#995792) - CVE-2016-7154: Use-after-free vulnerability in the FIFO event channel code in Xen allowed local guest OS administrators to cause a denial of service (host crash) and possibly execute arbitrary code or obtain sensitive information via an invalid guest frame number (bsc#997731) - CVE-2016-6836: VMWARE VMXNET3 NIC device allowed privileged user inside the guest to leak information.
