Flaw could unleash another Slammer

Core Security Technologies discovered that the Windows Workstation vulnerability announced by Microsoft last month could be exploited using the same type of data used by the SQL Slammer worm to spread across the Internet in just minutes.

"We believe these new attack vectors make the vulnerability even more dangerous and critical as the proposed workarounds are not sufficient to close them and particularly because they outline a very plausible scenario for a highly efficient worm," Ivan Arce, chief technology officer for security software maker Core Security Technologies, wrote in an e-mail to CNET News.com.

The companyís report also found that flaws in the Windows Messenger service, which allowed the MSBlast worm to spread this summer, could be exploited using the same "fire-and-forget" user datagram protocol (UDP) packets. The packets don't require two computers to establish a connection, which takes time. Instead, the source computer can quickly send out the packets and not worry about whether they reach their destination.
