1. Topic:

Updated sudo packages fixing a security problem are available.

2. Problem description:

Versions of sudo prior to 1.6.4 would not clear the environment before
sending an email notification about unauthorized sudo attempts, making it
possible for an attacker to supply parameters to the mail program. In the
worst case, this could lead to a local root exploit.

Users of sudo are advised to upgrade to version 1.6.4 which is not
vulnerable to this issue.

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

4. Relevant releases/architectures:

Red Hat Linux 7.0 - alpha, i386
Red Hat Linux 7.1 - alpha, i386, ia64
Red Hat Linux 7.2 - i386, ia64, s390

5. RPMs required:

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.

These packages are GPG signed by Red Hat, Inc. for security. Our key is available at:
http://www.redhat.com/about/contact.html

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

Note that you need RPM >= 3.0 to check GnuPG keys.
