    Synopsis
    ========

    Gaim is vulnerable to a buffer overflow which could lead to the
    execution of arbitrary code or 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 < 1.5.0 >= 1.5.0

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

    Brandon Perry discovered that Gaim is vulnerable to a heap-based buffer
    overflow when handling away messages (CAN-2005-2103). Furthermore,
    Daniel Atallah discovered a vulnerability in the handling of file
    transfers (CAN-2005-2102).

    Impact
    ======

    A remote attacker could create a specially crafted away message which,
    when viewed by the target user, could lead to the execution of
    arbitrary code. Also, an attacker could send a file with a non-UTF8
    filename to a user, which would result in a Denial of Service.

    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-1.5.0"
