"According to its self-reported version number, the Xen hypervisor installed on the remote host is affected by a denial
of service vulnerability. When the code processing grant table transfer requests finds a page with an address too large 
to be represented in the interface with the guest, it allocates a replacement page and copies page contents. However,
the code doing so fails to set the newly allocated page's accounting properties correctly, resulting in the page
becoming not only unusable by the target domain, but also unfreeable upon domain cleanup. The page as well as certain
other remnants of an affected guest will be leaked. Furthermore, the internal state of the processing code was also not
updated correctly, resulting in the insertion of an IOMMU mapping to the page being replaced (and subsequently freed),
allowing the domain access to memory it does not own. The primary impact is a memory leak. Malicious or buggy guests
with passed through PCI devices may also be able to escalate their privileges, crash the host, or access data belonging
to other guests.");

Security issues fixed :

CVE-2019-15890: Fixed a use-after-free in SLiRP networking
implementation of QEMU emulator which could have led to Denial of
Service (bsc#1149813).

CVE-2019-12068: Fixed an issue in lsi which could lead to an infinite
loop and denial of service (bsc#1146874).

CVE-2019-14378: Fixed a heap buffer overflow in SLiRp networking
implementation of QEMU emulator which could have led to execution of
arbitrary code with privileges of the QEMU process (bsc#1143797).

Other issues fixed: Fixed an HPS bug which did not allow to install
Windows Server 2016 with 2 CPUs setting or above (bsc#1137717).

Fixed a segmentation fault in Libvrtd during live migration to a VM
(bsc#1145774).

Fixed an issue where libxenlight could not create new domain
(bsc#1131811).

Fixed an issue where attached pci devices were lost after reboot
(bsc#1129642).

Fixed an issue where Xen could not pre-allocate 1 shadow page
(bsc#1145240).

Security issues fixed :

CVE-2019-15890: Fixed a use-after-free in SLiRP networking
implementation of QEMU emulator which could have led to Denial of
Service (bsc#1149813).

CVE-2019-12068: Fixed an issue in lsi which could lead to an infinite
loop and denial of service (bsc#1146874).

CVE-2019-14378: Fixed a heap buffer overflow in SLiRp networking
implementation of QEMU emulator which could have led to execution of
arbitrary code with privileges of the QEMU process (bsc#1143797).

Other issue fixed: Fixed an issue where libxenlight could not restore
domain vsa6535522 on live migration (bsc#1133818).

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable

CVE-2019-12068: Fixed an issue in lsi which could lead to an infinite
loop and denial of service (bsc#1146874).

CVE-2019-14378: Fixed a heap buffer overflow in SLiRp networking
