   An update that solves 14 vulnerabilities and has 5 fixes is
   now available.

Description:

   This update for xen fixes the following issues:

   Security issues fixed:

   - CVE-2018-18849: Fixed an out of bounds memory access issue that was
     found in the LSI53C895A SCSI Host Bus Adapter emulation while writing a
     message in lsi_do_msgin. It could occur during migration if the
     'msg_len' field has an invalid value. A user/process could use this flaw
     to crash the Qemu process resulting in DoS (bsc#1114423).
   - 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 in Bluetooth routines allows
     memory corruption (bsc#1117756).
   - CVE-2018-18438: Fixed an integer overflow in ccid_card_vscard_read
     function which allows memory corruption (bsc#1112188).
   - CVE-2018-17962: Fixed a Buffer Overflow in pcnet_receive in
     hw/net/pcnet.c because an incorrect integer data type is used
     (bsc#1111011).
   - 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-2018-19961 CVE-2018-19962: Fixed insufficient TLB flushing /
     improper large page mappings with AMD IOMMUs (XSA-275)(bsc#1115040).
   - CVE-2018-17963: Fixed qemu_deliver_packet_iov in net/net.c that accepts
     packet sizes greater than INT_MAX, which allows attackers to cause a
     denial of service or possibly have unspecified other impact.
     (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 a Buffer Overflow in rtl8139_do_receive in
     hw/net/rtl8139.c because an incorrect integer data type is used
     (bsc#1111007).
   - CVE-2018-10839: Fixed an integer overflow which could lead to a buffer
     overflow issue (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-2017-13672: Fixed an out of bounds read access during display update
     (bsc#1056336).
   - 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).
