Descriptions

Stack-based buffer overflow in the createAndJoinConference function in the AudioConf ActiveX control (yacscom.dll) in Yahoo! Messenger before 20070313 allows remote attackers to execute arbitrary code via long (1) socksHostname and (2) hostname properties.

Desbordamiento de búfer en la función createAndJoinConference en el control ActiveX AudioConf (yacscom.dll) en Yahoo! Messenger anterior a 20070313 permite a atacantes remotos ejecutar código de su elección a través de las propiedades (1) socksHostname y (2) hostname.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Yahoo Messenger. User interaction is required to exploit this vulnerability in that the target must visit a malicious page.
The specific flaw exists within the ActiveX control Yahoo.AudioConf:
DLL: yacscom.dllCLSID: 2B323CD9-50E3-11D3-9466-00A0C9700498
When large values are specified for the 'socksHostname' and 'hostname' properties, and the createAndJoinConference() method is called, a stack overflow occurs. Exploitation can result in code execution under the context of the current user.
