    <p>
    sysstat is a package containing a number of performance monitoring
    utilities for Linux, including sar, mpstat, iostat and sa tools
    </p>
  </background>
  <description>
    <p>
    There are two vulnerabilities in the way sysstat handles symlinks:
    </p>
	<ol>
    <li>The isag utility, which displays sysstat data in a graphical format,
    creates a temporary file in an insecure manner.</li>
    <li>Two scripts in the sysstat package, post and trigger, create temporary
    files in an insecure manner.</li>
	</ol>
  </description>
  <impact type="normal">
    <p>
    Both vulnerabilities may allow an attacker to overwrite arbitrary files
    under the permissions of the user executing any of the affected 
    utilities.
    </p>
  </impact>
  <workaround>
    <p>
    A workaround is not currently known for this issue. All users are advised
    to upgrade to the latest version of the affected package.
    </p>
  </workaround>
  <resolution>
    <p>
    Systat users should upgrade to version 4.2 or later:
    </p>
    <code>
    # emerge sync
    
    # emerge -pv ">=app-admin/sysstat-5.0.2"
    # emerge ">=app-admin/sysstat-5.0.2"</code>
  </resolution>
