Microsoft Security Bulletin MS02-029 - Unchecked Buffer in Remote Access Service Phonebook Could Lead to Code Execution. A flaw exists in the RAS phonebook implementation: a phonebook value is not properly checked, and is susceptible to a buffer overrun. The overrun could be exploited for either of two purposes: causing a system failure, or running code on the system with LocalSystem privileges. If an attacker were able to log onto an affected server and modify a phonebook entry using specially malformed data, then made a connection using the modified phonebook entry, the specially malformed data could be run as code by the system.
