CVE-2018-9063

MapDrv (C:\Program Files\Lenovo\System Update\mapdrv.exe) In Lenovo System Update versions earlier than 5.07.0072 contains a local vulnerability where an attacker entering very large user ID or password can overrun the program's buffer, causing undefined behaviors, such as execution of arbitrary code. No additional privilege is granted to the attacker beyond what is already possessed to run MapDrv.
