  <affected>
    <package name="kde-base/arts" auto="yes" arch="*">
      <unaffected range="ge">3.5.2-r1</unaffected>
      <unaffected range="rge">3.4.3-r1</unaffected>

  <background>
    <p>
    aRts is a real time modular system for synthesizing audio used by KDE.
    artswrapper is a helper application used to start the aRts daemon.
    </p>
  </background>
  <description>
    <p>
    artswrapper fails to properly check whether it can drop privileges
    accordingly if setuid() fails due to a user exceeding assigned resource
    limits.
    </p>
  </description>
  <impact type="high">
    <p>
    Local attackers could exploit this vulnerability to execute arbitrary
    code with elevated privileges. Note that the aRts package provided by
    Gentoo is only vulnerable if the artswrappersuid USE-flag is enabled.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All aRts users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose kde-base/arts</code>
  </resolution>
