Subject: [PATCH xserver 1/6] Xtest: disallow GenericEvents in
|
|
||||||
XTestSwapFakeInput
|
|
||||||
|
|
||||||
XTestSwapFakeInput assumes all events in this request are
|
|
||||||
sizeof(xEvent) and iterates through these in 32-byte increments.
|
|
||||||
However, a GenericEvent may be of arbitrary length longer than 32 bytes,
|
|
||||||
so any GenericEvent in this list would result in subsequent events to be
|
|
||||||
misparsed.
|
|
||||||
|
|
||||||
Additional, the swapped event is written into a stack-allocated struct
|
|
||||||
xEvent (size 32 bytes). For any GenericEvent longer than 32 bytes,
|
|
||||||
swapping the event may thus smash the stack like an avocado on toast.
|
|
||||||
|
|
||||||
Catch this case early and return BadValue for any GenericEvent.
|
|
||||||
Which is what would happen in unswapped setups anyway since XTest
|
|
||||||
doesn't support GenericEvent.

Subject: [PATCH xserver 3/6] Xi: avoid integer truncation in length check of
|
|
||||||
ProcXIChangeProperty
|
|
||||||
|
|
||||||
This fixes an OOB read and the resulting information disclosure.
|
|
||||||
|
|
||||||
Length calculation for the request was clipped to a 32-bit integer. With
|
|
||||||
the correct stuff->num_items value the expected request size was
|
|
||||||
truncated, passing the REQUEST_FIXED_SIZE check.
|
|
||||||
|
|
||||||
The server then proceeded with reading at least stuff->num_items bytes
|
|
||||||
(depending on stuff->format) from the request and stuffing whatever it
|
|
||||||
finds into the property. In the process it would also allocate at least
|
|
||||||
stuff->num_items bytes, i.e. 4GB.
|
|
||||||
|
|
||||||
The same bug exists in ProcChangeProperty and ProcXChangeDeviceProperty,
|
|
||||||
so let's fix that too.

Subject: [PATCH xserver 4/6] Xi: disallow passive grabs with a detail > 255
|
|
||||||
|
|
||||||
The XKB protocol effectively prevents us from ever using keycodes above
|
|
||||||
255. For buttons it's theoretically possible but realistically too niche
|
|
||||||
to worry about. For all other passive grabs, the detail must be zero
|
|
||||||
anyway.
|
|
||||||
|
|
||||||
This fixes an OOB write:
|
|
||||||
|
|
||||||
ProcXIPassiveUngrabDevice() calls DeletePassiveGrabFromList with a
|
|
||||||
temporary grab struct which contains tempGrab->detail.exact = stuff->detail.
|
|
||||||
For matching existing grabs, DeleteDetailFromMask is called with the
|
|
||||||
stuff->detail value. This function creates a new mask with the one bit
|
|
||||||
representing stuff->detail cleared.
|
|
||||||
|
|
||||||
However, the array size for the new mask is 8 * sizeof(CARD32) bits,
|
|
||||||
thus any detail above 255 results in an OOB array write.

Subject: [PATCH xserver 5/6] Xext: free the screen saver resource when

||||||
replacing it
|
|
||||||
|
|
||||||
This fixes a use-after-free bug:
|
|
||||||
|
|
||||||
When a client first calls ScreenSaverSetAttributes(), a struct

||||||
ScreenSaverAttrRec is allocated and added to the client's
|

resources.
|
|
||||||
|
|

When the same client calls ScreenSaverSetAttributes() again, a new

struct ScreenSaverAttrRec is allocated, replacing the old struct. The
|
|
||||||
old struct was freed but not removed from the clients resources.
|
|
||||||
|
|
||||||
Later, when the client is destroyed the resource system invokes
|
|
||||||
ScreenSaverFreeAttr and attempts to clean up the already freed struct.
|
|
||||||
|
|

Fix this by letting the resource system free the old attrs instead.

Subject: [PATCH xserver 6/6] Xext: free the XvRTVideoNotify when turning off
|
|
||||||
from the same client
|
|
||||||
|
|
||||||
This fixes a use-after-free bug:
|
|
||||||
|
|
||||||
When a client first calls XvdiSelectVideoNotify() on a drawable with a
|
|
||||||
TRUE onoff argument, a struct XvVideoNotifyRec is allocated. This struct
|
|
||||||
is added twice to the resources:
|
|
||||||
- as the drawable's XvRTVideoNotifyList. This happens only once per
|
|
||||||
drawable, subsequent calls append to this list.
|
|
||||||
- as the client's XvRTVideoNotify. This happens for every client.
|
|
||||||
|
|
||||||
The struct keeps the ClientPtr around once it has been added for a
|
|
||||||
client. The idea, presumably, is that if the client disconnects we can remove
|
|
||||||
all structs from the drawable's list that match the client (by resetting
|
|
||||||
the ClientPtr to NULL), but if the drawable is destroyed we can remove
|
|
||||||
and free the whole list.
|
|
||||||
|
|
||||||
However, if the same client then calls XvdiSelectVideoNotify() on the
|
|
||||||
same drawable with a FALSE onoff argument, only the ClientPtr on the
|
|
||||||
existing struct was set to NULL. The struct itself remained in the
|
|
||||||
client's resources.
|
|
||||||
|
|
||||||
If the drawable is now destroyed, the resource system invokes
|
|
||||||
XvdiDestroyVideoNotifyList which frees the whole list for this drawable
|
|
||||||
- including our struct. This function however does not free the resource
|
|
||||||
for the client since our ClientPtr is NULL.
|
|
||||||
|
|
||||||
Later, when the client is destroyed and the resource system invokes
|
|
||||||
XvdiDestroyVideoNotify, we unconditionally set the ClientPtr to NULL. On
|
|
||||||
a struct that has been freed previously. This is generally frowned upon.
|
|
||||||
|
|
||||||
Fix this by calling FreeResource() on the second call instead of merely
|
|
||||||
setting the ClientPtr to NULL. This removes the struct from the client
|
|
||||||
resources (but not from the list), ensuring that it won't be accessed
|
|
||||||
again when the client quits.
|
|
||||||
|
|
||||||
Note that the assignment tpn->client = NULL; is superfluous since the
|
|
||||||
XvdiDestroyVideoNotify function will do this anyway. But it's left for
|
|
||||||
clarity and to match a similar invocation in XvdiSelectPortNotify.

Subject: [PATCH xserver] xkb: reset the radio_groups pointer to NULL after
|
|
||||||
freeing it
|
|
||||||
|
|
||||||
Unlike other elements of the keymap, this pointer was freed but not
|
|
||||||
reset. On a subsequent XkbGetKbdByName request, the server may access
|
|
||||||
already freed memory.

fail somewhere.

Subject: [PATCH] xkb: proof GetCountedString against request length attacks
|
|
||||||
|
|
||||||
GetCountedString did a check for the whole string to be within the
|
|
||||||
request buffer but not for the initial 2 bytes that contain the length
|
|
||||||
field. A swapped client could send a malformed request to trigger a
|
|
||||||
swaps() on those bytes, writing into random memory.
