    descriptionThis 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). 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.

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).

"Upgrade the xen packages.

For the oldstable distribution (stretch), these problems have been
fixed in version 4.8.5.final+shim4.10.4-1+deb9u12. Note that this will
be the last security update for Xen in the oldstable distribution;
upstream support for the 4.8.x branch ended by the end of December
2019. If you rely on security support for your Xen installation an
update to the stable distribution (buster) is recommended.

For the stable distribution (buster), these problems have been fixed
in version 4.11.3+24-g14b62ab3e5-1~deb10u1."
