<description>
|
|
<p>
|
|
kadmind is affected by multiple vulnerabilities in the RPC library
|
|
shipped with MIT Kerberos 5. It fails to properly handle zero-length
|
|
RPC credentials (CVE-2007-2442) and the RPC library can write past the
|
|
end of the stack buffer (CVE-2007-2443). Furthermore kadmind fails to
|
|
do proper bounds checking (CVE-2007-2798).
|

|
|
<impact type="high">
|
|
<p>
|
|
A remote unauthenticated attacker could exploit these vulnerabilities
|
|
to execute arbitrary code with root privileges.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All MIT Kerberos 5 users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=app-crypt/mit-krb5-1.5.2-r3"</code>

</resolution>
