1. Topic:

A buffer overrun has been found in sudo.

2. 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.

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

29097 - buffer overflow in sudo

4. Relevant releases/architectures:

Red Hat Linux 7.0 - alpha, i386

5. RPMs required:

Red Hat Linux 7.0:

SRPMS:
ftp://updates.redhat.com/7.0/en/os/SRPMS/sudo-1.6.3p6-1.src.rpm

alpha:
ftp://updates.redhat.com/7.0/en/os/alpha/sudo-1.6.3p6-1.alpha.rpm

i386:
ftp://updates.redhat.com/7.0/en/os/i386/sudo-1.6.3p6-1.i386.rpm

6. Solution:

To update all RPMs for your particular architecture, run:

rpm -Fvh

where 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:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
