An update that fixes 15 vulnerabilities is now available.

Description:

This update for xen fixes the following issues:

  o CVE-2019-19581: Fixed a potential out of bounds on 32-bit Arm (bsc#1158003
    XSA-307).
  o 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).
  o 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).
  o 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).
  o 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).
  o 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).
  o 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).
  o CVE-2019-18420: Malicious x86 PV guests may have caused a hypervisor crash,
    resulting in a denial of service (bsc#1154448 XSA-296)
  o CVE-2019-18425: 32-bit PV guest user mode could elevate its privileges to
    that of the guest kernel. (bsc#1154456 XSA-298).
  o 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).
  o CVE-2019-18423: A malicious guest administrator may cause a hypervisor
    crash, resulting in a denial of service (bsc#1154460 XSA-301).
  o 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)
  o 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).
  o 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)
  o 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).

An update that fixes 9 vulnerabilities is now available.

Description:

This update for xen fixes the following issues:

  o CVE-2019-19581: Fixed a potential out of bounds on 32-bit Arm (bsc#1158003
    XSA-307).
  o 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).
  o 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).
  o 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).
  o 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).
  o 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).
  o 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).
  o CVE-2019-18423: A malicious guest administrator may cause a hypervisor
    crash, resulting in a Denial of Service (DoS) (bsc#1154460 XSA-301).
  o 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)
