    Description:
    
       This update for xen fixes the following issues:
    
       Security issues fixed:
    
       - 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-2018-18849: Fixed an out of bounds memory access issue was found in
         the LSI53C895A SCSI Host Bus Adapter emulation while writing a message
         in lsi_do_msgin (bsc#1114423).
       - 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-2018-18438: Fixed an integer overflow in ccid_card_vscard_read
         function which could allow memory corruption (bsc#1112188).
       - CVE-2018-17962: Fixed an integer overflow leading to a buffer overflow
         in the pcnet component (bsc#1111011)
       - 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 an untrusted PV domain with access to a
         physical device to DMA into its own pagetables leading to privilege
         escalation (bsc#1126195).
       - 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).
       - CVE-2018-17958: Fixed an integer overflow  which could lead to buffer
         overflow (bsc#1111007).
       - CVE-2018-10839: Fixed an integer overflow leading to a buffer overflow
         in the ne2000 component (bsc#1110924).
       - CVE-2019-6778: Fixed a heap buffer overflow in tcp_emu() found in slirp
         (bsc#1123157).
       - CVE-2018-19966: Fixed issue introduced by XSA-240 that could have caused
         conflicts with shadow paging (XSA-280)(bsc#1115047).
       - 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).
       - 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).
       - 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-2019-9824: Fixed an information leak in SLiRP networking
         implementation which could allow a user/process to read uninitialised
         stack memory contents (bsc#1129623).
