Alpine: multiple xen packages: security update to 4.3.2-r4 (deprecated)

critical Tenable Cloud Security Plugin ID 401191

Description

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

- The hvm_msr_read_intercept function in arch/x86/hvm/hvm.c in Xen 4.1 through 4.4.x uses an improper MSR
range for x2APIC emulation, which allows local HVM guests to cause a denial of service (host crash) or
read data from the hypervisor or other guests via unspecified vectors. (CVE-2014-7188)

- The HVMOP_set_mem_access HVM control operations in Xen 4.1.x for 32-bit and 4.1.x through 4.4.x for 64-bit
allow local guest administrators to cause a denial of service (CPU consumption) by leveraging access to
certain service domains for HVM guests and a large input. (CVE-2014-2599)

- The HVMOP_set_mem_type control in Xen 4.1 through 4.4.x allows local guest HVM administrators to cause a
denial of service (hypervisor crash) or possibly execute arbitrary code by leveraging a separate qemu-dm
vulnerability to trigger invalid page table translations for unspecified memory page types.
(CVE-2014-3124)

- The HVMOP_inject_msi function in Xen 4.2.x, 4.3.x, and 4.4.x does not properly check the return value from
the IRQ setup check, which allows local HVM guest administrators to cause a denial of service (NULL
pointer dereference and crash) via unspecified vectors. (CVE-2014-3967)

- The HVMOP_inject_msi function in Xen 4.2.x, 4.3.x, and 4.4.x allows local guest HVM administrators to
cause a denial of service (host crash) via a large number of crafted requests, which trigger an error
messages to be logged. (CVE-2014-3968)
