  <title>MIT Kerberos 5: Multiple local privilege escalation vulnerabilities</title>
  <synopsis>
    Some applications shipped with MIT Kerberos 5 are vulnerable to local
    privilege escalation.
  </synopsis>
  <product type="ebuild">MIT Kerberos 5</product>
  <announced>2006-08-10</announced>
  <revised>2006-08-10: 01</revised>
  <bug>143240</bug>
  <access>local</access>
  <affected>
    <package name="app-crypt/mit-krb5" auto="yes" arch="*">
      <unaffected range="ge">1.4.3-r3</unaffected>
      <vulnerable range="lt">1.4.3-r3</vulnerable>

  <background>
    <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.
    </p>

  <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 "&gt;=app-crypt/mit-krb5-1.4.3-r3"</code>
  </resolution>
