Description of problem:
If a tcpmux service is enabled, the user and group directives are ignored and the service always runs as root. Verified in the xinetd codebase and affects all active versions of RHEL and Fedora. Without the fix for CVE-2012-0862, previously exposed non-tcpmux services could run as root bypassing their respective user and group restrictions.
Version-Release number of selected component (if applicable):
2.3.15-6
How reproducible:
Always
Steps to Reproduce:
1. Enabled tcpmux-server
2. Create a sample tcpmux service

id = tcpmux-testcred
