"This update for xen fixes the following issues :

Update to Xen 4.11.1 bug fix release (bsc#1027519)

CVE-2018-17963: Fixed an integer overflow issue in the QEMU emulator,
which could occur when a packet with large packet size is processed. A
user inside a guest could have used this flaw to crash the qemu
process resulting in a Denial of Service (DoS). (bsc#1111014)

CVE-2018-18849: Fixed an out of bounds memory access in the LSI53C895A
SCSI host bus adapter emulation, which allowed a user and/or process
to crash the qemu process resulting in a Denial of Service (DoS).
(bsc#1114423)

CVE-2018-18883: Fixed an issue related to inproper restriction of
nested VT-x, which allowed a guest to cause Xen to crash, resulting in
a Denial of Service (DoS). (XSA-278) (bsc#1114405)

CVE-2018-19961, CVE-2018-19962: Fixed an issue related to insufficient
TLB flushing with AMD IOMMUs, which potentially allowed a guest to
escalate its privileges, may cause a Denial of Service (DoS) affecting
the entire host, or may be able to access data it is not supposed to
access. (XSA-275) (bsc#1115040)

CVE-2018-19963: Fixed the allocation of pages used to communicate with
external emulators, which may have cuased Xen to crash, resulting in a
Denial of Service (DoS). (XSA-276) (bsc#1115043)

CVE-2018-19965: Fixed an issue related to the INVPCID instruction in
case non-canonical addresses are accessed, which may allow a guest to
cause Xen to crash, resulting in a Denial of Service (DoS) affecting
the entire host. (XSA-279) (bsc#1115045)

CVE-2018-19966: Fixed an issue related to a previous fix for XSA-240,
which conflicted with shadow paging and allowed a guest to cause Xen
to crash, resulting in a Denial of Service (DoS) (XSA-280)
(bsc#1115047)

CVE-2018-19967: Fixed HLE constructs that allowed guests to lock up
the host, resulting in a Denial of Service (DoS). (XSA-282)
(bsc#1114988)

CVE-2018-19964: Fixed the incorrect error handling of p2m page
removals, which allowed a guest to cause a deadlock, resulting in a
Denial of Service (DoS) affecting the entire host. (XSA-277)
(bsc#1115044)

CVE-2018-19665: Fixed an integer overflow resulting in memory
corruption in various Bluetooth functions, allowing this to crash qemu
process resulting in Denial of Service (DoS). (bsc#1117756).

Other bugs fixed: Fixed an issue related to a domU hang on SLE12-SP3
HV (bsc#1108940)
