Summary
Security update for xen

Notes

Title of the patch
Security update for xen
Description of the patch
XEN was updated to fix two security issues and bugs. Security issues fixed: * CVE-2015-3340: Xen did not initialize certain fields, which allowed certain remote service domains to obtain sensitive information from memory via a (1) XEN_DOMCTL_gettscinfo or (2) XEN_SYSCTL_getdomaininfolist request. * CVE-2015-2751: Xen, when using toolstack disaggregation, allowed remote domains with partial management control to cause a denial of service (host lock) via unspecified domctl operations. * CVE-2015-2752: The XEN_DOMCTL_memory_mapping hypercall in Xen, when using a PCI passthrough device, was not preemptable, which allowed local x86 HVM domain users to cause a denial of service (host CPU consumption) via a crafted request to the device model (qemu-dm). * CVE-2015-3456: Fixed a buffer overflow in the floppy drive emulation, which could be used to denial of service attacks or potential code execution against the host. Bugs fixed: - xentop: Fix memory leak on read failure
