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).
The update package also includes non-security fixes. See advisory for details.
Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
