Description:

   This update for xen fixes the following issues:

   Security vulnerabilities fixed:

   - 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-2018-19965: 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-2018-19665: 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).
   - 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)

   Other bugs fixed:

   - Fixed an issue related to a domU hang on SLE12-SP3 HV (bsc#1108940)
   - Fixed an issue with xpti=no-dom0 not working as expected (bsc#1105528)
   - Fixed an issue with live migrations, which used to fail when spectre is
