A vulnerability was identified in Microsoft Windows, which could be exploited by remote attackers to execute arbitrary commands or by local users to obtain elevated privileges. This flaw is due to a buffer overflow error in the Telephony Application Programming Interface (TAPI) that does not properly handle specially crafted messages, which could be exploited by remote attackers to compromise a vulnerable system.
Note : On Windows 2000 Server, an anonymous attacker could remotely exploit this vulnerability. On Windows 2000 Professional and on Windows XP, this is a local elevation of privilege vulnerability. On Windows Server 2003, the Telephony service is restricted to authenticated user accounts.
