Miscreants have created an exploit capable of crashing Windows boxes and triggering the infamous Blue Screen of Death. The attack relies on exploiting an un-patched vulnerability in Microsoft’s implementation of Server Message Block, a network protocol involved in the sharing of files and printers on a network.
Windows 2000/XP are not affected by the exploit, but Windows 7is , and Vista and Server 2008 are all at risk. Proof-of-concept code demonstrating the vulnerability was published on Monday.
ISC researchers warns:
The exploit needs no authentication, only file sharing enabled with one packet to create a BSOD [Blue Screen of Death],
