SUMMARY

This article describes the following security issue in NetMeeting, and the patch that addresses the issue:

"Speed Dial" issue

Microsoft has posted a fix to protect NetMeeting customers against a potential problem known as the "Speed Dial" issue.

NetMeeting versions 2.0, 2.1 for Windows NT 4.0 on the following platforms: x86, Alpha
