3. Problem description:

The zip program is an archiving utility which can create ZIP-compatible
archives.

A buffer overflow bug has been discovered in zip when handling long file
names.  An attacker could create a specially crafted path which could
cause zip to crash or execute arbitrary instructions.  The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-2004-1010 to this issue.

Users of zip should upgrade to this updated package, which contains
backported patches and is not vulnerable to 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:

    http://www.redhat.com/docs/manuals/enterprise/

5. Bug IDs fixed (http://bugzilla.redhat.com/ for more info):

138228 - CAN-2004-1010 buffer overflow when creating archive containing very long filenames.
