Name of the Vulnerable Software and Affected Versions libcontainer versions prior to 0.5.3

Description The issue arises when creating a tenant container using libcontainer, where the tenant builder accepts a list of capabilities to be added to the spec of the tenant container. This logic can lead to the elevation of capabilities if inherited caps are set for the tenant container. The problem is specific to direct usage of libcontainer and its tenant builder, and does not affect the youki binary itself.

Recommendations For libcontainer versions prior to 0.5.3, update to version 0.5.3 or later to resolve the issue.
