Alpine: multiple xen packages: security update to 4.7.2-r0

critical Tenable Cloud Security Plugin ID 424713

Description

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

 - A heap buffer overflow flaw was found in QEMU's Cirrus CLGD 54xx VGA emulator's VNC display driver support
 before 2.9; the issue could occur when a VNC client attempted to update its display after a VGA operation
 is performed by a guest. A privileged user/process inside a guest could use this flaw to crash the QEMU
 process or, potentially, execute arbitrary code on the host with privileges of the QEMU process.
 (CVE-2016-9603)

 - An issue (known as XSA-212) was discovered in Xen, with fixes available for 4.8.x, 4.7.x, 4.6.x, 4.5.x,
 and 4.4.x. The earlier XSA-29 fix introduced an insufficient check on XENMEM_exchange input, allowing the
 caller to drive hypervisor memory accesses outside of the guest provided input/output arrays.
 (CVE-2017-7228)
