Security update for xen

This update for xen fixes the following issues:

  • A Mishandling of SYSCALL singlestep during emulation which could have lead to privilege escalation. (XSA-204, bsc#1016340, CVE-2016-10013)
  • CMPXCHG8B emulation failed to ignore operand size override which could have lead to information disclosure. (XSA-200, bsc#1012651, CVE-2016-9932)
  • PV guests may have been able to mask interrupts causing a Denial of Service. (XSA-202, bsc#1014298, CVE-2016-10024)
  • A missing NULL pointer check in VMFUNC emulation could lead to a hypervisor crash leading to a Denial of Servce. (XSA-203, bsc#1014300, CVE-2016-10025)

Описание

Xen through 4.8.x allows local 64-bit x86 HVM guest OS users to gain privileges by leveraging mishandling of SYSCALL singlestep during emulation.

Описание

Xen through 4.8.x allows local x86 PV guest OS kernel administrators to cause a denial of service (host hang or crash) by modifying the instruction stream asynchronously while performing certain kernel operations.

Описание

VMFUNC emulation in Xen 4.6.x through 4.8.x on x86 systems using AMD virtualization extensions (aka SVM) allows local HVM guest OS users to cause a denial of service (hypervisor crash) by leveraging a missing NULL pointer check.

Описание

CMPXCHG8B emulation in Xen 3.3.x through 4.7.x on x86 systems allows local HVM guest OS users to obtain sensitive information from host stack memory via a "supposedly-ignored" operand size prefix.
