Alpine: xen: security update to 4.16.5-r5

low Tenable Self-Hosted Container Security Plugin ID 408172

Description

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

 - Arm provides multiple helpers to clean & invalidate the cache for a given region. This is, for instance,
 used when allocating guest memory to ensure any writes (such as the ones during scrubbing) have reached
 memory before handing over the page to a guest. Unfortunately, the arithmetics in the helpers can overflow
 and would then result to skip the cache cleaning/invalidation. Therefore there is no guarantee when all
 the writes will reach the memory. This undefined behavior was meant to be addressed by XSA-437, but the
 approach was not sufficient. (CVE-2023-46837)
