Detail

Synopsis

A vulnerability in xinetd could lead to privilege escalation.

Background

xinetd is a secure replacement for inetd.

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"
