FreeBSD : FreeBSD -- Kernel stack disclosure in setlogin(2) / getlogin(2) (74389f22-6007-11e6-a6c3-14dae9d210b8)

When setlogin2 is called while setting up a new login session, the login name is copied into an uninitialized stack buffer, which is then copied into a buffer of the same size in the session structure. The getlogin2 system call returns the entire buffer rather than just the portion occupied by th...
