An update that fixes 8 vulnerabilities is now available.

Description:

This update for xen fixes several issues:

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 occured 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)
