<p>
MIT Kerberos 5 is a suite of applications that implement the Kerberos
network protocol. It is designed to provide strong authentication for
client/server applications by using secret-key cryptography.

<description>
<p>
Unchecked calls to setuid() in krshd and v4rcp, as well as unchecked
calls to seteuid() in kftpd and in ksu, have been found in the MIT
Kerberos 5 program suite and may lead to a local root privilege
escalation.
</p>
</description>
<impact type="high">
<p>
A local attacker could exploit this vulnerability to execute arbitrary
code with elevated 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 &quot;&gt;=app-crypt/mit-krb5-1.4.3-r3&quot;</code>
</resolution>
