1. Topic:

Updated namazu packages are available for Red Hat Linux 7.0J. These
packages fix cross-site scripting vulnerabilities. It also fixes a possible
buffer overflow.

2. Relevant releases/architectures:

Red Hat Linux 7.0J - i386

3. Problem description:

Namazu is a full-text search engine. Namazu 2.0.9 and earlier may
inadvertently include malicious HTML tags or scripts in a dynamically
generated page, based on unvalidated input from untrustworthy sources.
Also, a buffer overflow vulnerability exists in the buffer size of an
environment variable.

These packages update Namazu to version 2.0.10 which is not vulnerable to
these issues.

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.
