Red Hat: An updated sos package fixes one security issue

Sos is a set of tools that gather information about system hardware and configuration. The sosreport utility incorrectly included Certificate-based Red Hat Network private entitlement keys in the resulting archive of debugging information. An attacker able to access the archive could use the keys to access Red Hat Network content available to the host. Updated packages are available from ftp.redhat.com.
