"The version of Pidgin installed on the remote host is a version prior
to 2.10.8. It is, therefore, potentially affected by the following
vulnerabilities :

  - The bundled version of Pango has an error that can lead
    to an application crash when rendering fonts and
    attempting to display certain Unicode characters. 

  - Errors exist related to handling unspecified
    characters, incorrect character encoding, incorrect
    XMPP timestamps, hovering a pointer over a long URL,
    unspecified HTTP responses, Yahoo! P2P messages, STUN
    responses, and IRC arguments that could cause
    application crashes and denial of service conditions.

    CVE-2013-6479, CVE-2013-6481, CVE-2013-6484,
    CVE-2014-0020)

  - Errors exist related to handling MSN SOAP, MSN OIM, and
    MSN header content that could cause application
    crashes when NULL pointers are dereferenced.
    (CVE-2013-6482)

  - An error exists related XMPP content such that the
    'from' portion of some 'iq' replies is not verified.
    (CVE-2013-6483)

  - Errors exist related to parsing chunked and
    Gadu-Gadu HTTP content, MXit emoticons, and
    SIMPLE headers that could allow buffer overflows.
    (CVE-2013-6485, CVE-2013-6487, CVE-2013-6489,
    CVE-2013-6490)

  - The application does not protect against links to
    untrusted executable content. (CVE-2013-6486)");
