    <p>
    Pidgin (formerly Gaim) is an instant messaging client for a variety of
    instant messaging protocols. It is based on the libpurple instant
    messaging library.
    </p>
  </background>
  <description>
    <p>
    Multiple vulnerabilities have been discovered in Pidgin and the
    libpurple library:
    </p>
    <ul><li>
    A participant to the TippingPoint ZDI reported multiple integer
    overflows in the msn_slplink_process_msg() function in the MSN protocol
    implementation (CVE-2008-2927).
    </li>
    <li>
    Juan Pablo Lopez Yacubian is credited for reporting a use-after-free
    flaw in msn_slplink_process_msg() in the MSN protocol implementation
    (CVE-2008-2955).
    </li>
    <li>
    The included UPnP server does not limit the size of data to be
    downloaded for UPnP service discovery, according to a report by Andrew
    Hunt and Christian Grothoff (CVE-2008-2957).
    </li>
    <li>
    Josh Triplett discovered that the NSS plugin for libpurple does not
    properly verify SSL certificates (CVE-2008-3532).
    </li>
    </ul>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could send specially crafted messages or files using
    the MSN protocol which could result in the execution of arbitrary code
    or crash Pidgin. NOTE: Successful exploitation might require the
    victim's interaction. Furthermore, an attacker could conduct
    man-in-the-middle attacks to obtain sensitive information using bad
    certificates and cause memory and disk resources to exhaust.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Pidgin users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=net-im/pidgin-2.5.1&quot;</code>
  </resolution>
