"This update for xen fixes the following issues :

Security vulnerabilities fixed :

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-2018-19965: 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-2018-19966: 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-2018-19665: 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-2018-18849: Fixed an out of bounds memory access in the LSI53C895A
SCSI host bus adapter emulation, which allowed a user and/or process
to crash the qemu process resulting in a Denial of Service (DoS).
(bsc#1114423)

Other bugs fixed: Fixed an issue related to a domU hang on SLE12-SP3
HV (bsc#1108940)

Fixed an issue with xpti=no-dom0 not working as expected (bsc#1105528)

Fixed an issue with live migrations, which used to fail when spectre
is enabled on xen boot cmdline (bsc#1116380)

Upstream bug fixes (bsc#1027519)

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."

"This update for xen fixes the following issues :

Security issues fixed :

  - 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-2019-6778: Fixed a heap buffer overflow in tcp_emu()
    found in slirp (bsc#1123157).

  - 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).

  - 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-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 insufficient TLB
    flushing / improper large page mappings with AMD IOMMUs
    (XSA-275)(bsc#1115040).

  - CVE-2018-19965: Fixed denial of service issue from
    attempting to use INVPCID with a non-canonical addresses
    (XSA-279)(bsc#1115045).

  - CVE-2018-19966: Fixed issue introduced by XSA-240 that
    could have caused conflicts with shadow paging
    (XSA-280)(bsc#1115047).

  - 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).

  - Fixed an issue which could allow malicious 64bit PV
    guests to cause a host crash (bsc#1127400).

  - Fixed an issue which could allow malicious or buggy x86
    PV guest kernels to mount a Denial of Service attack
    affecting the whole system (bsc#1126197).

  - 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).

Other issues addressed :

  - Upstream bug fixes (bsc#1027519)

  - Fixed an issue where live migrations were failing when
    spectre was enabled on xen boot cmdline (bsc#1116380).

  - Fixed an issue where setup of grant_tables and other
    variables may fail (bsc#1126325).

  - Fixed a building issue (bsc#1119161).

  - Fixed an issue where xpti=no-dom0 was not working as
    expected (bsc#1105528).

  - Packages should no longer use /var/adm/fillup-templates
    (bsc#1069468). 

  - Added Xen cmdline option 'suse_vtsc_tolerance' to avoid
    TSC emulation for HVM domUs (bsc#1026236).

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

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).

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
