       An update that solves 15 vulnerabilities and has 10 fixes
       is now available.
    
    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).
