Description Bryn M. Reeves 2007-02-28 11:06:45 UTC
Description of problem:
The diskdumputils RPM re-uses the netdump user and group accounts as the owner
of /var/crash. This account needs a login shell for netdump to allow the
client-side initscript (propagate/start) to function.

For diskdump this appears unnecessary causes concern for some security concious
diskdump users.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Ensure netdump is not installed
2. Install the diskdump RPM
3. run:
$ getent passwd netdump
Actual results:
netdump:x:34:34:Network Crash Dump user:/var/crash:/bin/bash

Expected results:
netdump:x:34:34:Network Crash Dump user:/var/crash:/sbin/nologin
(Or similar - not having a login shell set when it is not required is the
desired change)

Additional info:
I guess one way to address this would be to create a "crashdump" group that owns
the /var/crash hierarchy and has write permissions to create dumps. The
different dump packages could then add their own accounts (netdump, diskdump) as
members of this group.
