Description wingc 2000-02-18 01:10:34 UTC
I sent this same bug report in for RH 6.1, but haven't received a response

The identd daemon in RH 6.2 beta 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'

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 can be found at:
