Notes

Title of the patch
Security update for xen
Description of the patch
This update for xen to version 4.7.2 fixes the following issues: These security issues were fixed: - CVE-2017-7228: Broken check in memory_exchange() permited PV guest breakout (bsc#1030442). - XSA-206: Unprivileged guests issuing writes to xenstore were able to stall progress of the control domain or driver domain, possibly leading to a Denial of Service (DoS) of the entire host (bsc#1030144). - CVE-2017-6505: The ohci_service_ed_list function in hw/usb/hcd-ohci.c allowed local guest OS users to cause a denial of service (infinite loop) via vectors involving the number of link endpoint list descriptors (bsc#1028235). These non-security issues were fixed: - bsc#1015348: libvirtd didn't not start during boot - bsc#1014136: kdump couldn't dump a kernel on SLES12-SP2 with Xen hypervisor. - bsc#1026236: Fixed paravirtualized performance - bsc#1022555: Timeout in 'execution of /etc/xen/scripts/block add' - bsc#1029827: Forward port xenstored - bsc#1029128: Make xen to really produce xen.efi with gcc48
