Alpine: multiple xen packages: security update to 4.9.0-r7

critical Tenable Cloud Security Plugin ID 424754

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - An issue was discovered in Xen through 4.9.x. Grant copying code made an implication that any grant pin
 would be accompanied by a suitable page reference. Other portions of code, however, did not match up with
 that assumption. When such a grant copy operation is being done on a grant of a dying domain, the
 assumption turns out wrong. A malicious guest administrator can cause hypervisor memory corruption, most
 likely resulting in host crash and a Denial of Service. Privilege escalation and information leaks cannot
 be ruled out. (CVE-2017-15597)
