Description

Microsoft Internet Information Services (IIS) is prone to an overflow condition. The 'TELNET_STREAM_CONTEXT::OnSendData' function in the FTP protocol handler (ftpsvc.dll) fails to properly sanitize user-supplied input resulting in a heap-based overflow. With a specially crafted overly long FTP request, a remote attacker can potentially execute arbitrary code.
