---------------------------------------------------------------------

1. Topic:

Updated sudo packages fixing a security problem are available.

2. 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

3. 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.

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.
