An update that solves three vulnerabilities and has 9 fixes
is now available.

Description:

This update for qemu fixes the following issues:

Security issues fixed:

- CVE-2019-14378: Security fix for heap overflow in ip_reass on big packet
input (bsc#1143794).
- CVE-2019-12155: Security fix for null pointer dereference while
releasing spice resources (bsc#1135902).
- CVE-2019-13164: Security fix for qemu-bridge-helper ACL can be bypassed
when names are too long (bsc#1140402).

Bug fixes and enhancements:

- Add vcpu features needed for Cascadelake-Server, Icelake-Client and
Icelake-Server, especially the foundational arch-capabilities to help
with security and performance on Intel hosts (bsc#1134880) (fate#327764).
- Add support for one more security/performance related vcpu feature
(bsc#1136777) (fate#327795).
- Disable file locking in the Xen PV disk backend to avoid locking issues
with PV domUs during migration. The issues triggered by the locking can
not be properly handled in libxl. The locking introduced in qemu-2.10
was removed again in qemu-4.0 (bsc#1079730, bsc#1098403, bsc#1111025).
- Ignore csske for expanding the cpu model (bsc#1136528).
- Provide qcow2 L2 caching improvements, which allows for better storage
performance in certain configurations (bsc#1139926, ECO-130).
- Fixed virsh migrate-setspeed (bsc#1127077, bsc#1141043).
