code (CVE-2009-4893).</li>

<impact type="high">
<p>
A remote attacker could exploit these vulnerabilities to cause the
execution of arbitrary commands with the privileges of the user running
UnrealIRCd, or a Denial of Service condition. NOTE: By default
UnrealIRCd on Gentoo is run with the privileges of the "unrealircd"
user.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All UnrealIRCd users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=net-irc/unrealircd-3.2.8.1-r1&quot;</code>
