Security update for qemu

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).

Описание

qemu-bridge-helper.c in QEMU 3.1 and 4.0.0 does not ensure that a network interface name (obtained from bridge.conf or a --br=bridge option) is limited to the IFNAMSIZ size, which can lead to an ACL bypass.

Описание

ip_reass in ip_input.c in libslirp 4.0.0 has a heap-based buffer overflow via a large packet because it mishandles a case involving the first fragment.
