    Synopsis
    ========

    Multiple vulnerabilities have been found in Gaim which could allow a
    remote attacker to crash the application, or possibly execute
    arbitrary code.

    Background
    ==========

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

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

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 net-im/gaim < 1.0.2 >= 1.0.2

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

    A possible buffer overflow exists in the code processing MSN SLP
    messages (CAN-2004-0891). memcpy() was used without validating the size
    of the buffer, and an incorrect buffer was used as destination under
    certain circumstances. Additionally, memory allocation problems were
    found in the processing of MSN SLP messages and the receiving of files.
    These issues could lead Gaim to try to allocate more memory than
    available, resulting in the crash of the application.

    Impact
    ======

    A remote attacker could crash Gaim and possibly execute arbitrary code
    by exploiting the buffer overflow.

    Workaround
    ==========

    There is no known workaround at this time.

    Resolution
    ==========

    All Gaim users should upgrade to the latest version:

        # emerge sync

        # emerge -pv ">=net-im/gaim-1.0.2"
        # emerge ">=net-im/gaim-1.0.2"
