Alpine: xen: security update to 4.6.3-r9

high Tenable Self-Hosted Container Security Plugin ID 407866

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- Xen through 4.8.x on 64-bit platforms mishandles page tables after an IRET hypercall, which might allow PV
guest OS users to execute arbitrary code on the host OS, aka XSA-213. (CVE-2017-8903)

- Xen through 4.8.x mishandles the "contains segment descriptors" property during GNTTABOP_transfer (aka
guest transfer) operations, which might allow PV guest OS users to execute arbitrary code on the host OS,
aka XSA-214. (CVE-2017-8904)

- Xen through 4.6.x on 64-bit platforms mishandles a failsafe callback, which might allow PV guest OS users
to execute arbitrary code on the host OS, aka XSA-215. (CVE-2017-8905)

- A parameter verification issue was discovered in Xen through 4.9.x. The function `alloc_heap_pages` allows
callers to specify the first NUMA node that should be used for allocations through the `memflags`
parameter; the node is extracted using the `MEMF_get_node` macro. While the function checks to see if the
special constant `NUMA_NO_NODE` is specified, it otherwise does not handle the case where `node >=
MAX_NUMNODES`. This allows an out-of-bounds access to an internal array. (CVE-2017-14316)
