  <synopsis>
    Multiple vulnerabilities in MIT Kerberos 5 could potentially result in the
    execution of arbitrary code.

  <affected>
    <package name="app-crypt/mit-krb5" auto="yes" arch="*">

  <background>
    <p>
    MIT Kerberos 5 is a suite of applications that implement the Kerberos
    network protocol.
    </p>
  </background>
  <description>
    <p>
    The Kerberos administration daemon, and possibly other applications
    using the GSS-API or RPC libraries, could potentially call a function
    pointer in a freed heap buffer, or attempt to free an uninitialized
    pointer.
    </p>
  </description>
  <impact type="high">
    <p>
    A remote attacker may be able to crash an affected application, or
    potentially 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 &quot;&gt;=app-crypt/mit-krb5-1.5.2&quot;</code>
  </resolution>
