Asianux Server 7 for x86_64

The kernel packages contain the Linux kernel, the core of any Linux operating system.

These updated kernel packages include several security issues and numerous
bug fixes, some of which you can see below. Space precludes documenting
all of these bug fixes in this advisory. To see the complete list of bug
fixes, users are directed to the related Knowledge Article:

Security Fix(es):

* Kernel: KVM: MMU potential stack buffer overrun during page walks (CVE-2017-12188, Important)

* Kernel: KVM: debug exception via syscall emulation (CVE-2017-7518, Moderate)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

arch/x86/kvm/mmu.c in the Linux kernel through 4.13.5, when nested
virtualisation is used, does not properly traverse guest pagetable
entries to resolve a guest virtual address, which allows L1 guest OS
users to execute arbitrary code on the host OS or cause a denial of
service (incorrect index during page walking, and host OS crash), aka
an "MMU potential stack buffer overrun."
This candidate has been reserved by an organization or individual that
will use it when announcing a new security problem. When the
