Unspecified vulnerability in Microsoft NetMeeting 3.01 allows remote attackers to cause a denial of service (crash or CPU consumption) and possibly execute arbitrary code via crafted inputs that trigger memory corruption.

The Remote Desktop Sharing (RDS) Screen Saver Protection capability for Microsoft NetMeeting 3.01 through SP2 (4.4.3396) allows attackers with physical access to hijack remote sessions by entering certain logoff or shutdown sequences (such as CTRL-ALT-DEL) and canceling out of the resulting user confirmation prompts, such as when the remote user is editing a document.

Microsoft NetMeeting 3.01 with Remote Desktop Sharing enabled allows remote attackers to cause a denial of service via a malformed string to the NetMeeting service port, aka a variant of the "NetMeeting Desktop Sharing" vulnerability.
