<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.

<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
