Detailed Description
Business Impact: MS07-019 patches a critical stack overflow in Microsoft Universal Plug and Play (UPNP). The UPNP service listens on UDP port 1900 and TCP port 2869 on computers that have an attached UPNP capable hardware device or are running a UPNP configured service such as Internet Connection Sharing. This stack overflow is easily exploited and provides an attacker with complete control over the victim PC.

Technical Description: Microsoft Windows is vulnerable to a buffer overflow, caused by improper bounds checking by the Universal Plug and Play (UPnP) service. By sending a specially-crafted HTTP request, a remote attacker could overflow a buffer and execute arbitrary code on the system with elevated privileges when combined with another exploit.
Remediation: Apply the appropriate patch for your system, as listed in Microsoft Security Bulletin MS07-019. See References.
