Red Hat, Inc. Red Hat Security Advisory
Synopsis: Updated xinetd package available for Red Hat Linux 7 and 7.1
Advisory ID: RHSA-2001:075-04

Updated on: 2001-06-05
Product: Red Hat Linux
Keywords: xinetd umask 2.4 kernel linuxconf
Cross references:
Obsoletes:
- ---------------------------------------------------------------------
1. Topic:
Xinetd runs with umask 0 - this means that applications using the xinetd
umask and not setting the permissions themselves (like swat from the samba
package), will create world writable files.
2. Relevant releases/architectures:
Red Hat Linux 7.0 - alpha, i386
Red Hat Linux 7.1 - i386
3. Problem description:
Xinetd runs with umask 0 - this means that applications using the xinetd
umask and not setting the permissions themselves (like swat from the samba
package), will create world writable files. This update sets the default
umask to 022. Also, the web interface for linuxconf did not work in Red Hat
Linux 7.1. Other minor issues have also been addressed.
4. Solution:
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
To update all RPMs for your particular architecture, run:
rpm -Fvh [filenames]
where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which are
not installed but included in the list will not be updated. Note that you
can also use wildcards (*.rpm) if your current directory *only* contains the
desired RPMs.
Please note that this update is also available via Red Hat Network. Many
people find this an easier way to apply updates. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:
up2date
This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info):
38669 - /etc/xinetd.d/*-udp files syntax error on
23560 - xinetd - linuxconf-web still not fixed
