Summary:

Microsoft Windows could allow a local attacker to terminate programs without authorization, caused by a vulnerability in the PostThreadMessage API. The PostThreadMessage API allows a program to send a WM_QUIT, WM_CLOSE, or WM_DESTROY message to another program's thread on the same desktop to close the program. If the specified thread has a message queue, a local attacker could exploit this vulnerability to terminate processes, such as antivirus applications, personal firewall applications, filtering applications, and monitoring applications without permission.
