[RHSA-2001:019-02] Updated sudo packages fixing buffer overrun available

                   Red Hat, Inc. Red Hat Security Advisory

Synopsis:          Updated sudo packages fixing buffer overrun available
Advisory ID:       RHSA-2001:019-02
Issue date:        2001-02-23
Updated on:        2001-03-21
Product:           Red Hat Powertools
Keywords:          sudo buffer overrun
Cross references:  RHSA-2001:018-01

1. Topic:

An overrunnable buffer exists in sudo versions prior to 1.6.3p6

2. Relevant releases/architectures:

Red Hat Powertools 6.2 - alpha, i386, sparc

3. Problem description:

The code splitting a log entry into smaller chunks contained an
overrunnable buffer. Carefully constructed long commands could lead to
execution of code as root. There is no known exploit at this time.

4. Solution:

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 directly *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:


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):

29097 - buffer overflow in sudo

6. RPMs required:

Red Hat Powertools 6.2:





7. Verification:

MD5 sum                           Package Name

These packages are GPG signed by Red Hat, Inc. for security.  Our key
is available at:

You can verify each package with the following command:
    rpm --checksig  <filename>

If you only wish to verify that each package has not been corrupted or
tampered with, examine only the md5sum with the following command:
    rpm --checksig --nogpg <filename>
