Synopsis
========
A vulnerability in xinetd could lead to privilege escalation.
Background
==========
xinetd is a secure replacement for inetd.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 sys-apps/xinetd < 2.3.15-r2 >= 2.3.15-r2
Description
===========
Xinetd does not enforce the user and group configuration directives for
TCPMUX services, which causes these services to be run as root.
Impact
======
Attackers could escalate privileges outside of the running process.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All xinetd users should upgrade to the latest version:
# emerge --sync
# emerge --ask --verbose --oneshot ">=sys-apps/xinetd-2.3.15-r2"
