Red Hat Bugzilla – Bug 9206
identd runs as root, not nobody
Last modified: 2008-05-01 11:37:54 EDT
The identd daemon in Red Hat 6.1 runs as the root user, not 'nobody', which
is unnecessary and for all I know may lead to a security compromise. There
are actually 2 separate bugs:
1. in /etc/inetd.conf, identd is run as 'root' instead of 'nobody'
(this should be marked as a bug in netkit-base, I know)
2. (more importantly) the identd code is multithreaded but is not aware of
the fact that threads do not share UIDs in Linux. This causes some of the
identd threads to run as root when identd is started from init. identd also
fails to drop supplimental group IDs, which results in it having group ID 0
A fix against pidentd-3.0.10, the version in the current Raw Hide, is
