From Secunia:
Description:
A vulnerability has been reported in Yahoo! Messenger, which can be exploited by malicious people to compromise a user’s system.
The vulnerability is caused due to a boundary error within the AudioConf ActiveX control (yacscom.dll) component of Yahoo! Messenger. This can be exploited to cause a stack-based buffer overflow by setting the “socksHostname” and “hostName” properties to an overly large string and then calling the “createAndJoinConference()” method.
Successful exploitation allows execution of arbitrary code when a user visits a malicious web site.
The vulnerability is reported in version 8.x. Other versions may also be affected.
