2. Problem description:

A security audit has been done by Solar Designer on xinetd, and the
results are now being made available as a preemptive measure. Also,
memsetting too much memory to 0 would eventually lead to segfaults when
executing services. This internal bug was fixed.

3. Bug IDs fixed: (see bugzilla for more information)

48367 - telnet service fails after a couple of hours with xinetd-2.3.0
51737 - xinetd does not register all rpc versions with the portmapper

4. Relevant releases/architectures:

Red Hat Linux 7.0 - alpha, i386
Red Hat Linux 7.1 - alpha, i386, ia64

5. RPMs required:

Red Hat Linux 7.0:

SRPMS:
ftp://updates.redhat.com/7.0/en/os/SRPMS/xinetd-2.3.3-1.src.rpm

alpha:
ftp://updates.redhat.com/7.0/en/os/alpha/xinetd-2.3.3-1.alpha.rpm

i386:
ftp://updates.redhat.com/7.0/en/os/i386/xinetd-2.3.3-1.i386.rpm

Red Hat Linux 7.1:

SRPMS:
ftp://updates.redhat.com/7.1/en/os/SRPMS/xinetd-2.3.3-1.src.rpm

alpha:
ftp://updates.redhat.com/7.1/en/os/alpha/xinetd-2.3.3-1.alpha.rpm

i386:
ftp://updates.redhat.com/7.1/en/os/i386/xinetd-2.3.3-1.i386.rpm

ia64:
ftp://updates.redhat.com/7.1/en/os/ia64/xinetd-2.3.3-1.ia64.rpm

6. 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.

7. Verification:

MD5 sum                           Package Name
