    <p>
    Qpopper is a widely used server for the POP3 protocol.

  <description>
    <p>
    Jens Steube discovered that Qpopper doesn't drop privileges to
    process local files from normal users (CAN-2005-1151). The upstream
    developers discovered that Qpopper can be forced to create group or
    world writeable files (CAN-2005-1152).
    </p>
  </description>
  <impact type="normal">
    <p>
    A malicious local attacker could exploit Qpopper to overwrite
    arbitrary files as root or create new files which are group or world
    writeable.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Qpopper users should upgrade to the latest available version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=net-mail/qpopper-4.0.5-r3"</code>
