   An update that fixes 15 vulnerabilities is now available.

Description:

   This update for xen fixes the following issues:

   - CVE-2019-19581: Fixed a potential out of bounds on 32-bit Arm
     (bsc#1158003 XSA-307).
   - 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-2019-18420: Malicious x86 PV guests may have caused a hypervisor
     crash, resulting in a denial of service (bsc#1154448 XSA-296)
   - CVE-2019-18425: 32-bit PV guest user mode could elevate its privileges
     to that
     of the guest kernel. (bsc#1154456 XSA-298).
   - CVE-2019-18421: A malicious PV guest administrator may have been able to
     escalate their privilege to that of the host. (bsc#1154458 XSA-299).
   - CVE-2019-18423: A malicious guest administrator may cause a hypervisor
     crash, resulting in a denial of service  (bsc#1154460 XSA-301).
   - CVE-2019-18422: A malicious ARM guest might contrive to arrange for
     critical Xen code to run with interrupts erroneously enabled. This could
     lead to data corruption, denial of service, or possibly even privilege
     escalation. However a precise attack technique has not been identified.
     (bsc#1154464 XSA-303)
   - CVE-2019-18424: An untrusted domain with access to a physical device can
     DMA into host memory, leading to privilege escalation. (bsc#1154461
     XSA-302).
   - CVE-2018-12207: Untrusted virtual machines on Intel CPUs could exploit a
     race condition in the Instruction Fetch Unit of the Intel CPU to cause a
     Machine Exception during Page Size Change, causing the CPU core to be
     non-functional. (bsc#1155945 XSA-304)
   - CVE-2019-11135: Aborting an asynchronous TSX operation on Intel CPUs
     with Transactional Memory support could be used to facilitate
     sidechannel information leaks out of microarchitectural buffers, similar
     to the previously described "Microarchitectural Data Sampling"
 attack.
     (bsc#1152497 XSA-305).
