 Overview : The host is running Pidgin, which is prone to integer
 overflow vulnerability.
 
 Vulnerability Insight:

        The flaw is caused due to errors in the msn_slplink_process_msg
        function in libpurple/protocols/msnp9/slplink.c and
        libpurple/protocols/msn/slplink.c files, which fails to perform
        adequate boundary checks on user-supplied data.

        Impact : Remote attacker can execute arbitrary code by sending
        specially crafted SLP message with the privilege of a user.
 
 Impact Level : SYSTEM
 
 Affected Software/OS:
        Pidgin Version prior to 2.4.3 on Linux (All).
