xinetd: Privilege escalation — GLSA 201611-06

A vulnerability in xinetd could lead to privilege escalation.

Package	sys-apps/xinetd on all architectures
Affected versions	< 2.3.15-r2
Unaffected versions	>= 2.3.15-r2

xinetd is a secure replacement for inetd.

Xinetd does not enforce the user and group configuration directives for TCPMUX services, which causes these services to be run as root.

Attackers could escalate privileges outside of the running process.

There is no known workaround at this time.

All xinetd users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --verbose --oneshot ">=sys-apps/xinetd-2.3.15-r2"
