A security vulnerability exists in the Help & Support Center function which ships with Windows XP & Windows Server 2003. The affected code is also included in all other supported Windows operating systems, although no known attack vector has been identified at this time because the HCP protocol is not supported on those platforms. The vulnerability results because a file associated with the HCP protocol contains an unchecked buffer.
