utilities for Linux, including sar, mpstat, iostat and sa tools
</p>

<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>
