--- Comment #1 from CTurt <ertl.ch...@gmail.com> --- Sorry, made a mistake in my report. Supplying a size of `-1` actually passes `0xffffffffffffffff` to `malloc` and `copyin`. However, since `malloc` truncates sizes to 32bit (at least version 9.0 did), this will result in an allocation of `0xffffffff`, but copy length of `0xffffffffffffffff`. If there is enough memory for this allocation to succeed, a heap overflow will occur. -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ freebsd-bugs@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "freebsd-bugs-unsubscr...@freebsd.org"
