    remote code execution with root privileges by unauthenticated users.

    MIT Kerberos 5 is a suite of applications that implement the Kerberos
    network protocol.

  <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).
    </p>
  </description>
  <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 "&gt;=app-crypt/mit-krb5-1.5.2-r3"</code>
  </resolution>
