Alpine: multiple xen packages: security update to 4.9.0-r5 (deprecated)

high Tenable Cloud Security Plugin ID 400780

Description

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

 - An issue was discovered in Xen through 4.9.x allowing x86 PV guest OS users to cause a denial of service
 (unbounded recursion, stack consumption, and hypervisor crash) or possibly gain privileges via crafted
 page-table stacking. (CVE-2017-15595)

 - An issue was discovered in Xen through 4.9.x allowing x86 PV guest OS users to execute arbitrary code on
 the host OS because of a race condition that can cause a stale TLB entry. (CVE-2017-15588)

 - An issue was discovered in Xen through 4.9.x allowing x86 HVM guest OS users to obtain sensitive
 information from the host OS (or an arbitrary guest OS) because intercepted I/O operations can cause a
 write of data from uninitialized hypervisor stack memory. (CVE-2017-15589)

 - An issue was discovered in Xen through 4.9.x allowing x86 guest OS users to cause a denial of service
 (hypervisor crash) or possibly gain privileges because MSI mapping was mishandled. (CVE-2017-15590)

 - An issue was discovered in Xen through 4.9.x allowing x86 HVM guest OS users to cause a denial of service
 (hypervisor crash) or possibly gain privileges because self-linear shadow mappings are mishandled for
 translated guests. (CVE-2017-15592)
