This update for xen fixes the following issues :
A Mishandling of SYSCALL singlestep during emulation which could have lead to privilege escalation. (XSA-204, bsc#1016340, CVE-2016-10013)
CMPXCHG8B emulation failed to ignore operand size override which could have lead to information disclosure. (XSA-200, bsc#1012651, CVE-2016-9932)
PV guests may have been able to mask interrupts causing a Denial of Service. (XSA-202, bsc#1014298, CVE-2016-10024)
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.
