    Synopsis
    ========

    Gaim contains a remotely exploitable buffer overflow vulnerability in
    the MSN-protocol parsing code that may allow remote execution of
    arbitrary code.

    Background
    ==========

    Gaim is a multi-protocol instant messaging client for Linux which
    supports many instant messaging protocols.

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

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected

      1 net-im/gaim <= 0.81 >= 0.81-r1

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

    Sebastian Krahmer of the SuSE Security Team has discovered a remotely
    exploitable buffer overflow vulnerability in the code handling MSN
    protocol parsing.

    Impact
    ======

    By sending a carefully-crafted message, an attacker may execute
    arbitrary code with the permissions of the user running Gaim.

    Workaround
    ==========

    There is no known workaround at this time. All users are encouraged to
    upgrade to the latest available version of Gaim.

    Resolution
    ==========

    All Gaim users should upgrade to the latest version:

        # emerge sync

        # emerge -pv ">=net-im/gaim-0.81-r1"
        # emerge ">=net-im/gaim-0.81-r1"
