Terminal Server Client username buffer overflow
|terminal-server-username-bo (65101)||High Risk|
Terminal Server Client (tsclient) is vulnerable to a stack-based buffer overflow, caused by improper bounds checking by the tsc_launch_remote() function when processing the username parameter. By persuading a victim to open a specially-crafted RDP file containing an overly long string, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
No remedy available as of May 1, 2013.
