3. Problem description:

Sysreport is a utility that gathers information about a system's hardware
and configuration. The information can then be used for diagnostic purposes
and debugging.

Bill Stearns discovered a bug in the way sysreport creates temporary files.
It is possible that a local attacker could obtain sensitive information
about the system when sysreport is run. The Common Vulnerabilities and
Exposures project assigned the name CAN-2005-2104 to this issue.

Users of sysreport should update to this erratum package, which contains a
patch that resolves this issue.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

This update is available via Red Hat Network.  To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

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