  <description>This update for xen fixes the following issues:

Security issues fixed:

- CVE-2019-6778: Fixed a heap buffer overflow in tcp_emu() found in slirp (bsc#1123157).
- CVE-2017-13672: Fixed an out of bounds read access during display update (bsc#1056336).
- Fixed an issue which could allow malicious or buggy guests with passed through PCI devices to  be able to 
  escalate their privileges, crash the host, or access data belonging to other guests. Additionally memory 
  leaks were also possible (bsc#1126140)
- Fixed a race condition issue which could allow malicious PV guests to escalate their privilege to that 
  of the hypervisor (bsc#1126141).
- CVE-2018-18849: Fixed an out of bounds msg buffer access which could lead to denial of service (bsc#1114423).  
- Fixed an issue which could allow a malicious unprivileged guest userspace process to escalate its privilege 
  to that of other userspace processes in the same guest and potentially thereby to that 
  of the guest operating system (bsc#1126201).  
- CVE-2018-17958: Fixed an integer overflow leading to a buffer overflow in the
  rtl8139 component (bsc#1111007)
- 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-2018-19665: 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-2019-9824: Fixed an information leak in SLiRP networking implementation which could allow a user/process 
  to read uninitialised stack memory contents (bsc#1129623).
- 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-2018-19966: 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-2018-10839: Fixed an integer overflow leading to a buffer overflow in
  the ne2000 component (bsc#1110924).
- 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).
- Fixed an issue which could allow malicious 64bit PV guests to cause a host crash (bsc#1127400).
- Fixed an issue which could allow malicious PV guests may cause a host crash or 
  gain access to data pertaining to other guests.Additionally, vulnerable configurations 
  are likely to be unstable even in the absence of an attack (bsc#1126198).
- Fixed multiple access violations introduced by XENMEM_exchange hypercall which could allow 
  a single PV guest to leak arbitrary amounts of memory, leading to a denial of service (bsc#1126192).
- CVE-2018-17963: Fixed an integer overflow in relation to large packet sizes,
  leading to a denial of service (DoS). (bsc#1111014).
- Fixed an issue which could allow a malicious or buggy x86 PV guest kernels can mount a Denial of Service
  attack affecting the whole system (bsc#1126196).
- Fixed an issue which could allow an untrusted PV domain with access to a physical device to DMA into its own 
  pagetables leading to privilege escalation (bsc#1126195).
- CVE-2018-17962: Fixed an integer overflow leading to a buffer overflow in the
  pcnet component (bsc#1111011)
- CVE-2018-18438: Fixed an integer overflow in ccid_card_vscard_read function which could lead to memory corruption (bsc#1112188).

Other issues fixed:

- Upstream bug fixes (bsc#1027519)
- Fixed an issue where XEN SLE12-SP1 domU hangs on SLE12-SP3 HV1108940 (bsc#1108940).
