Yahoo! Messenger AudioConf ActiveX Control (yacscom.dll) Multiple Property Overflow

high Nessus Plugin ID 24913

Synopsis

The remote Windows host has an ActiveX control that is affected by a buffer vulnerability.

Description

The remote host contains a version of the 'AudioConf' ActiveX control included with Yahoo! Messenger.

The version of this ActiveX control on the remote host has a buffer overflow triggered by calling the control's 'createAndJoinConference' method with large values for the 'socksHostname' and 'hostname' properties. If an attacker can trick a user on the affected host into visiting a specially crafted web page, this issue could be leveraged to execute arbitrary code on the host subject to the user's privileges.

Solution

Update to the latest version of Yahoo! Messenger and ensure that the version of the control is at least 1.0.0.48 or higher.
