"This update for xen 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 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
has attempted to automatically clean and format it as much as possible
without introducing additional issues.");
