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-2018-19967: 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-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)
Fixed an integer overflow in ccid_card_vscard_read(), which allowed for
memory corruption. (bsc#1112188)
CVE-2017-13672: Fixed an out of bounds read access during display update
(bsc#1056336)
CVE-2018-17958: Fixed an integer overflow leading to a buffer overflow
in the rtl8139 component (bsc#1111007)
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)
CVE-2018-10839: Fixed an integer overflow leading to a buffer overflow
in the ne2000 component (bsc#1110924)
Other bugs fixed:
Fixed an issue related to a domU hang on SLE12-SP3 HV (bsc#1108940)
Upstream bug fixes (bsc#1027519)
Fixed crashing VMs when migrating between dom0 hosts (bsc#1031382)
Fixed an issue with xpti=no-dom0 not working as expected (bsc#1105528)");
