Alpine: multiple xen packages: security update to 4.2.2-r5 (deprecated)

critical Tenable Cloud Security Plugin ID 401147

Description

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

- Xen 4.1.x and 4.2.x, when the XSA-45 patch is in place, does not properly maintain references on pages
stored for deferred cleanup, which allows local PV guest kernels to cause a denial of service (premature
page free and hypervisor crash) or possibly gain privileges via unspecified vectors. (CVE-2013-1432)

- Certain page table manipulation operations in Xen 4.1.x, 4.2.x, and earlier are not preemptible, which
allows local PV kernels to cause a denial of service via vectors related to "deep page table traversal."
(CVE-2013-1918)
