Advanced Micro Devices Inc will steer clear of established 64-bit computing vendors when its launches its Opteron architecture later this year, and will instead aim its attack squarely at long-time 32-bit rival Intel Corp
The vendor's Opteron architecture, previously codenamed Hammer, will offer customers the choice of 32-bit or 64-bit operation. The architecture will be the newest entrant to the 64-bit space after Intel, which launched its Itanium architecture in 2001, but which has yet to pick up steam in the market.
AMD claims that by offering the ability to run existing 32-bit applications, without tweaking, while also offering customers the ability to run more powerful 64 applications when they are ready, Opteron is a more palatable proposition for companies looking to make the leap to 64-bit

MS02-044 (Q328130): Unsafe Functions in Office Web Components
The Office Web Components (OWC) contain several ActiveX controls that give users limited functionality of Microsoft Office in a web browser without requiring that the user install the full Microsoft Office application. This allows users to utilize Microsoft Office applications in situations where installation of the full application is infeasible or undesirable.
The control contains three security vulnerabilities, each of which could be exploited either via a web site or an HTML mail.

SMB (Server Message Block) is the protocol Microsoft uses to share files, printers, serial ports, and also to communicate between computers using named pipes and mail slots. In a networked environment, servers make file systems and resources available to clients. Clients make SMB requests for resources and servers make SMB responses in what described as a client server, request-response protocol.
By sending a specially crafted packet request, an attacker can mount a denial of service attack on the target server machine and crash the system. The attacker could use both a user account and anonymous access to accomplish this. Though not confirmed, it may be possible to execute arbitrary code.

A security vulnerability results because the control contains an unchecked buffer in the code that processes one of the input parameters. By calling the control on a client system and overrunning the buffer, an attacker could gain the ability to run code in the security context of the currently logged on user. This would enable the attacker to take any desired action on the user's system. The attacker could mount an attack by either hosting a web page that exploits the vulnerability against any user who visits it, or by sending an HTML mail to another user.
