These security issues were fixed:

- CVE-2017-5526: The ES1370 audio device emulation support was vulnerable to a
 memory leakage issue allowing a privileged user inside the guest to cause a DoS
 and/or potentially crash the Qemu process on the host (bsc#1059777)
- CVE-2017-15593: Missing cleanup in the page type system allowed a malicious or
 buggy PV guest to cause DoS (XSA-242 bsc#1061084)
- CVE-2017-15592: A problem in the shadow pagetable code allowed a malicious or
 buggy HVM guest to cause DoS or cause hypervisor memory corruption potentially
 allowing the guest to escalate its privilege (XSA-243 bsc#1061086)
- CVE-2017-15594: Problematic handling of the selector fields in the Interrupt
 Descriptor Table (IDT) allowed a malicious or buggy x86 PV guest to escalate
 its privileges or cause DoS (XSA-244 bsc#1061087)
- CVE-2017-15589: Intercepted I/O write operations with less than a full machine
 word's worth of data were not properly handled, which allowed a malicious
 unprivileged x86 HVM guest to obtain sensitive information from the host or
 other guests (XSA-239 bsc#1061080)
- CVE-2017-15595: In certain configurations of linear page tables a stack overflow
 might have occurred that allowed a malicious or buggy PV guest to cause DoS and
 potentially privilege escalation and information leaks (XSA-240 bsc#1061081)
- CVE-2017-15588: Under certain conditions x86 PV guests could have caused the
 hypervisor to miss a necessary TLB flush for a page. This allowed a malicious
 x86 PV guest to access all of system memory, allowing for privilege escalation,
 DoS, and information leaks (XSA-241 bsc#1061082)
- CVE-2017-15590: Multiple issues existed with the setup of PCI MSI interrupts
 that allowed a malicious or buggy guest to cause DoS and potentially privilege
 escalation and information leaks (XSA-237 bsc#1061076)");
