  <title>kdebase: KDM vulnerabilities</title>
  <synopsis>
    A bug in KDM can allow privilege escalation with certain configurations of
    PAM modules.

    <package name="kde-base/kdebase" auto="yes" arch="*">

    <p>
    KDM is the desktop manager included with the K Desktop Environment.
    </p>

  <description>
    <p>
    Firstly, versions of KDM &lt;=3.1.3 are vulnerable to a privilege escalation
    bug with a specific configuration of PAM modules.  Users who do not use PAM
    with KDM and users who use PAM with regular Unix crypt/MD5 based
    authentication methods are not affected.
    </p>
    <p>
    Secondly, KDM uses a weak cookie generation algorithm.  Users are advised to
    upgrade to KDE 3.1.4, which uses /dev/urandom as a non-predictable source of
    entropy to improve security.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote or local attacker could gain root privileges.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    It is recommended that all Gentoo Linux users who are running
    kde-base/kdebase &lt;=3.1.3 upgrade:
    </p>
    <code>
    # emerge sync
    # emerge -pv '&gt;=kde-base/kde-3.1.4'
    # emerge '&gt;=kde-base/kde-3.1.4'
    # emerge clean</code>
  </resolution>
