Classifying Illegal Datagram Causes Browser Access Violation

 Last reviewed: November 5, 1997
Article ID: Q105737

The information in this article applies to:
  • Microsoft Windows NT operating system version 3.1
  • Microsoft Windows NT Advanced Server version 3.1

SYMPTOMS

There is a bug in the BROWSER.SYS driver that can occur when processing an illegal datagram on streams transports. If the datagram passed in is shorter than will fit in a valid transaction Server Message Block (SMB), the browser checks beyond the end of the buffer, possibly doing access violation.

STATUS

Microsoft has confirmed this to be a problem in Windows NT and Windows NT Advanced Server version 3.1. This problem was corrected in the latest U.S. Service Pack for Windows NT and Windows NT Advanced Server version 3.1.
