3. Problem description:

Mod_python is a module that embeds the Python language interpreter within
the Apache web server, allowing handlers to be written in Python.

Graham Dumpleton discovered a flaw affecting the publisher handler of
mod_python, used to make objects inside modules callable via URL.  
A remote user could visit a carefully crafted URL that would gain access to
objects that should not be visible, leading to an information leak.  The
Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned
the name CAN-2005-0088 to this issue.

Users of mod_python are advised to upgrade to this updated package,
which contains a backported patch to correct this issue.

4. Solution:

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.  Use Red Hat
Network to download and update your packages.  To launch the Red Hat
Update Agent, use the following command:

    up2date

For information on how to install packages manually, refer to the
following Web page for the System Administration or Customization
guide specific to your system:
