[NTOS] Addendum to 03873aee: check that the computed size of the OEM-converted string is less than MAXUSHORT. 2018-12-21 00:34:56 +01:00

[NTOSKRNL] Check that caller has the priviliege to unload a driver 
Also, probe the service name when unloading a driver if called from
user-mode. This will avoid that userland applications can trigger an
invalid read in the kernel (and thus, a BSOD).

[NTOS] Addendum to d8cb37bf: return the correct Status from NtAllocateUuids(). 2018-12-20 03:47:45 +01:00
Hermès Bélusca-Maïto 03873aeef3
[NTOS] Fixes for NtDisplayString(). 
- Require the user to have TCB privilege for using this function.
- Probe and capture the user-provided string (and avoid usermode-triggered BSODS ;-)
- Allocate the OEM-converted string in *NonPagedPool* because we are
  going to transmit the buffer to BOOTVID.

[NTOSKRNL] Probe parameters in NtAllocateUuids() if called from user-mode 
This will avoid that userland applications can trigger an invalid write in
the kernel (and thus, a BSOD).

[NTOSKRNL] Only allow SYSTEM to call NtSetUuidSeed() 
Also, validate input buffer before attempting any operation on it.
This will avoid userland applications to be able to trigger an invalid
read in the kernel (and thus a BSOD).

Regarding access restriction, see:

Pierre Schweitzer 182cc5c5ab
[NTOSKRNL] Don't dereference VACB when allocating its memory area fails 
This avoids performing a double-free (even though that's hidden by the
fact we use lookaside allocations for VACB), and it avoids freeing
a memory address at an uninitialized address.
We don't care about references here, the VACB was just allocated, never
linked and we're its only user.

Spotted by Thomas :-)
 2018-11-11 23:21:36 +01:00
Hermès Bélusca-Maïto cbaa8e7dfb
[NTOS:IO] RAW-FS: Few improvements. 
- Simplify the volume-deletion code in RawCheckForDismount().

- Fixes the OpenCount check in RawClose(): the VCB mutex must be
  released when the volume has not been dismounted, either because
  OpenCount != 0 or because RawCheckForDismount() returned FALSE.

- Explicitly use VCB_STATE_LOCKED instead of hardcoding its value.

- In IRP_MN_VERIFY_VOLUME handling, lock the volume before playing
  with it, and again let the volume be dismounted only if OpenCount == 0
  (and the IoDeleteDevice() call is done by RawCheckForDismount()).
