CVE-2019-19582: Fixed a potential infinite loop when x86 accesses to
bitmaps with a compile time known size of 64 (bsc#1158003 XSA-307).

CVE-2019-19583: Fixed improper checks which could have allowed HVM/PVH
guest userspace code to crash the guest,leading to a guest denial of
service (bsc#1158004 XSA-308).

CVE-2019-19578: Fixed an issue where a malicious or buggy PV guest
could have caused hypervisor crash resulting in denial of service
affecting the entire host (bsc#1158005 XSA-309).

CVE-2019-19580: Fixed a privilege escalation where a malicious PV
guest administrator could have been able to escalate their privilege
to that of the host (bsc#1158006 XSA-310).

CVE-2019-19577: Fixed an issue where a malicious guest administrator
could have caused Xen to access data structures while they are being
modified leading to a crash (bsc#1158007 XSA-311).

CVE-2019-19579: Fixed a privilege escaltion where an untrusted domain
with access to a physical device can DMA into host memory (bsc#1157888
XSA-306).

CVE-2019-18423: A malicious guest administrator may cause a hypervisor

    non-functional. (bsc#1155945)

  - CVE-2019-11135: Aborting an asynchronous TSX operation

    used to facilitate sidechannel information leaks out of
    microarchitectural buffers, similar to the previously
    described 'Microarchitectural Data Sampling' attack.

  - CVE-2019-18422: A malicious ARM guest might contrive to

  - CVE-2019-18421: A malicious PV guest administrator may
