"This update for xen to version 4.11.2 fixes the following issues :

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).
