    Synopsis
    ========

    Gaim contains multiple vulnerabilities that can lead to a Denial of
    Service.

    Background
    ==========

    Gaim is a full featured instant messaging client which handles a
    variety of instant messaging protocols.

    Affected packages
    =================

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 net-im/gaim < 1.2.1 >= 1.2.1

    Description
    ===========

    Multiple vulnerabilities have been addressed in the latest release of
    Gaim:

    * A buffer overread in the gaim_markup_strip_html() function, which
      is used when logging conversations (CAN-2005-0965).

    * Markup tags are improperly escaped using Gaim's IRC plugin
      (CAN-2005-0966).

    * Sending a specially crafted file transfer request to a Gaim Jabber
      user can trigger a crash (CAN-2005-0967).

    Impact
    ======

    An attacker could possibly cause a Denial of Service by exploiting any
    of these vulnerabilities.

    Workaround
    ==========

    There is no known workaround at this time.

    Resolution
    ==========

    All Gaim users should upgrade to the latest version:

        # emerge --sync
        # emerge --ask --oneshot --verbose ">=net-im/gaim-1.2.1"
