Multiple vulnerabilities have been reported in UnrealIRCd:
|
||
|
|
</p>
|
||
|
|
<ul>
|
||
|
|
<li>The vendor reported a buffer overflow in the user authorization
|
||
|
|
code (CVE-2009-4893).</li>
|
||
|
|
<li>The vendor reported that the distributed source code of UnrealIRCd
|
||
|
|
was compromised and altered to include a system() call that could be
|
||
|
|
called with arbitrary user input (CVE-2010-2075).</li>
|
||
|
|
</ul>
|
||
|

<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.
