Subject: [PATCH] Xi/randr: fix handling of PropModeAppend/Prepend
|
||||||
|
|
||||||
|
The handling of appending/prepending properties was incorrect, with at
|
||||||
|
least two bugs: the property length was set to the length of the new
|
||||||
|
part only, i.e. appending or prepending N elements to a property with P
|
||||||
|
existing elements always resulted in the property having N elements
|
||||||
|
instead of N + P.
|
||||||
|
|
||||||
|
Second, when pre-pending a value to a property, the offset for the old
|
||||||
|
values was incorrect, leaving the new property with potentially
|
||||||
|
uninitalized values and/or resulting in OOB memory writes.
|
||||||
|
For example, prepending a 3 element value to a 5 element property would
|
||||||
|
result in this 8 value array:
|
||||||
|
[N, N, N, ?, ?, P, P, P ] P, P
|
||||||
|
^OOB write
|
||||||
|
|
||||||
|
The XI2 code is a copy/paste of the RandR code, so the bug exists in
|
||||||
|
both.

Subject: [PATCH] mi: reset the PointerWindows reference on screen switch
|
||||||
|
|
||||||
|
PointerWindows[] keeps a reference to the last window our sprite
|
||||||
|
entered - changes are usually handled by CheckMotion().
|
||||||
|
|
||||||
|
If we switch between screens via XWarpPointer our
|
||||||
|
dev->spriteInfo->sprite->win is set to the new screen's root window.
|
||||||
|
If there's another window at the cursor location CheckMotion() will
|
||||||
|
trigger the right enter/leave events later. If there is not, it skips
|
||||||
|
that process and we never trigger LeaveWindow() - PointerWindows[] for
|
||||||
|
the device still refers to the previous window.
|
||||||
|
|
||||||
|
If that window is destroyed we have a dangling reference that will
|
||||||
|
eventually cause a use-after-free bug when checking the window hierarchy
|
||||||
|
later.
|
||||||
|
|
||||||
|
To trigger this, we require:
|
||||||
|
- two protocol screens
|
||||||
|
- XWarpPointer to the other screen's root window
|
||||||
|
- XDestroyWindow before entering any other window
|
||||||
|
|
||||||
|
This is a niche bug so we hack around it by making sure we reset the
|
||||||
|
PointerWindows[] entry so we cannot have a dangling pointer. This
|
||||||
|
doesn't handle Enter/Leave events correctly but the previous code didn't
|
||||||
|
either.

|
button->xkb_acts is supposed to be an array sufficiently large for all

our buttons, not just a single XkbActions struct. Allocating
|

|
insufficient memory here means when we memcpy() later in

XkbSetDeviceInfo we write into memory that wasn't ours to begin with,

leading to the usual security ooopsiedaisies.

Subject: [PATCH] randr: avoid integer truncation in length check of
|
||||||
|
ProcRRChange*Property
|
||||||
|
|
||||||
|
Affected are ProcRRChangeProviderProperty and ProcRRChangeOutputProperty.
|
||||||
|
See also xserver@8f454b79 where this same bug was fixed for the core
|
||||||
|
protocol and XI.
|
||||||
|
|
||||||
|
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->nUnits 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->nUnits bytes, i.e. 4GB.

Subject: [PATCH 2/9] dix: Allocate sufficient xEvents for our
|
||||||
|
DeviceStateNotify
|
||||||
|
|
||||||
|
If a device has both a button class and a key class and numButtons is
|
||||||
|
zero, we can get an OOB write due to event under-allocation.
|
||||||
|
|
||||||
|
This function seems to assume a device has either keys or buttons, not
|
||||||
|
both. It has two virtually identical code paths, both of which assume
|
||||||
|
they're applying to the first event in the sequence.
|
||||||
|
|
||||||
|
A device with both a key and button class triggered a logic bug - only
|
||||||
|
one xEvent was allocated but the deviceStateNotify pointer was pushed on
|
||||||
|
once per type. So effectively this logic code:
|
||||||
|
|
||||||
|
int count = 1;
|
||||||
|
if (button && nbuttons > 32) count++;
|
||||||
|
if (key && nbuttons > 0) count++;
|
||||||
|
if (key && nkeys > 32) count++; // this is basically always true
|
||||||
|
// count is at 2 for our keys + zero button device
|
||||||
|
|
||||||
|
ev = alloc(count * sizeof(xEvent));
|
||||||
|
FixDeviceStateNotify(ev);
|
||||||
|
if (button)
|
||||||
|
FixDeviceStateNotify(ev++);
|
||||||
|
if (key)
|
||||||
|
FixDeviceStateNotify(ev++); // santa drops into the wrong chimney here
|
||||||
|
|
||||||
|
If the device has more than 3 valuators, the OOB is pushed back - we're
|
||||||
|
off by one so it will happen when the last deviceValuator event is
|
||||||
|
written instead.
|
||||||
|
|
||||||
|
Fix this by allocating the maximum number of events we may allocate.
|
||||||
|
Note that the current behavior is not protocol-correct anyway, this
|
||||||
|
patch fixes only the allocation issue.
|
||||||
|
|
||||||
|
Note that this issue does not trigger if the device has at least one
|
||||||
|
button. While the server does not prevent a button class with zero
|
||||||
|
buttons, it is very unlikely.

Subject: [PATCH 3/9] dix: fix DeviceStateNotify event calculation
|
||||||
|
|
||||||
|
The previous code only made sense if one considers buttons and keys to
|
||||||
|
be mutually exclusive on a device. That is not necessarily true, causing
|
||||||
|
a number of issues.
|
||||||
|
|
||||||
|
This function allocates and fills in the number of xEvents we need to
|
||||||
|
send the device state down the wire. This is split across multiple
|
||||||
|
32-byte devices including one deviceStateNotify event and optional
|
||||||
|
deviceKeyStateNotify, deviceButtonStateNotify and (possibly multiple)
|
||||||
|
deviceValuator events.
|
||||||
|
|
||||||
|
The previous behavior would instead compose a sequence
|
||||||
|
of [state, buttonstate, state, keystate, valuator...]. This is not
|
||||||
|
protocol correct, and on top of that made the code extremely convoluted.
|
||||||
|
|
||||||
|
Fix this by streamlining: add both button and key into the deviceStateNotify
|
||||||
|
and then append the key state and button state, followed by the
|
||||||
|
valuators. Finally, the deviceValuator events contain up to 6 valuators
|
||||||
|
per event but we only ever sent through 3 at a time. Let's double that
|
||||||
|
troughput.

Subject: [PATCH 4/9] Xi: when creating a new ButtonClass, set the number of
|
||||||
|
buttons
|
||||||
|
|
||||||
|
There's a racy sequence where a master device may copy the button class
|
||||||
|
from the slave, without ever initializing numButtons. This leads to a
|
||||||
|
device with zero buttons but a button class which is invalid.
|
||||||
|
|
||||||
|
Let's copy the numButtons value from the source - by definition if we
|
||||||
|
don't have a button class yet we do not have any other slave devices
|
||||||
|
with more than this number of buttons anyway.

Subject: [PATCH 5/9] Xi: flush hierarchy events after adding/removing master
|
||||||
|
devices
|
||||||
|
|
||||||
|
The `XISendDeviceHierarchyEvent()` function allocates space to store up
|
||||||
|
to `MAXDEVICES` (256) `xXIHierarchyInfo` structures in `info`.
|
||||||
|
|
||||||
|
If a device with a given ID was removed and a new device with the same
|
||||||
|
ID added both in the same operation, the single device ID will lead to
|
||||||
|
two info structures being written to `info`.
|
||||||
|
|
||||||
|
Since this case can occur for every device ID at once, a total of two
|
||||||
|
times `MAXDEVICES` info structures might be written to the allocation.
|
||||||
|
|
||||||
|
To avoid it, once one add/remove master is processed, send out the
|
||||||
|
device hierarchy event for the current state and continue. That event
|
||||||
|
thus only ever has exactly one of either added/removed in it (and
|
||||||
|
optionally slave attached/detached).
|
||||||
|
|
||||||
|

Subject: [PATCH 6/9] Xi: do not keep linked list pointer during recursion
|
||||||
|
|
||||||
|
The `DisableDevice()` function is called whenever an enabled device
|
||||||
|
is disabled and it moves the device from the `inputInfo.devices` linked
|
||||||
|
list to the `inputInfo.off_devices` linked list.
|
||||||
|
|
||||||
|
However, its link/unlink operation has an issue during the recursive
|
||||||
|
call to `DisableDevice()` due to the `prev` pointer pointing to a
|
||||||
|
removed device.
|
||||||
|
|
||||||
|
This issue leads to a length mismatch between the total number of
|
||||||
|
devices and the number of device in the list, leading to a heap
|
||||||
|
overflow and, possibly, to local privilege escalation.
|
||||||
|
|
||||||
|
Simplify the code that checked whether the device passed to
|
||||||
|
`DisableDevice()` was in `inputInfo.devices` or not and find the
|
||||||
|
previous device after the recursion.

||||||

Subject: [PATCH 7/9] dix: when disabling a master, float disabled slaved
|
||||||
|
devices too
|
||||||
|
|
||||||
|
Disabling a master device floats all slave devices but we didn't do this
|
||||||
|
to already-disabled slave devices. As a result those devices kept their
|
||||||
|
reference to the master device resulting in access to already freed
|
||||||
|
memory if the master device was removed before the corresponding slave
|
||||||
|
device.
|
||||||
|
|
||||||
|
And to match this behavior, also forcibly reset that pointer during
|
||||||
|
CloseDownDevices().

Subject: [PATCH 4/4] render: fix refcounting of glyphs during
|
||||||
|
ProcRenderAddGlyphs
|
||||||
|
|
||||||
|
Previously, AllocateGlyph would return a new glyph with refcount=0 and a
|
||||||
|
re-used glyph would end up not changing the refcount at all. The
|
||||||
|
resulting glyph_new array would thus have multiple entries pointing to
|
||||||
|
the same non-refcounted glyphs.
|
||||||
|
|
||||||
|
AddGlyph may free a glyph, resulting in a UAF when the same glyph
|
||||||
|
pointer is then later used.
|
||||||
|
|
||||||
|
Fix this by returning a refcount of 1 for a new glyph and always
|
||||||
|
incrementing the refcount for a re-used glyph, followed by dropping that
|
||||||
|
refcount back down again when we're done with it.
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
The problem is caused by dev->master being not reset when disabling the
|
||||||
|
device, which then causes dangling pointer when the master device itself
|
||||||
|
is being deleted when exiting whole server.
|
||||||
|
|
||||||
|
Note that RecalculateMasterButtons() requires dev->master to be still
|
||||||
|
valid, so we can reset it only at the end of function.

Subject: [PATCH] vncsession: use /bin/sh if the user shell is not set
|
|
||||||
|
|
||||||
An empty shell field in the password file is valid, although not common.
|
|
||||||
Use /bin/sh in this case, as documented in the passwd(5) man page, since
|
|
||||||
the vncserver script requires a non-empty SHELL environment variable.
|
|
||||||
|
|
||||||
Fixes issue #1786.

Subject: [PATCH] render: Avoid possible double-free in ProcRenderAddGlyphs()
|
||||||
|
|
||||||
|
ProcRenderAddGlyphs() adds the glyph to the glyphset using AddGlyph() and
|
||||||
|
then frees it using FreeGlyph() to decrease the reference count, after
|
||||||
|
AddGlyph() has increased it.
|
||||||
|
|
||||||
|
AddGlyph() however may chose to reuse an existing glyph if it's already
|
||||||
|
in the glyphSet, and free the glyph that was given, in which case the
|
||||||
|
caller function, ProcRenderAddGlyphs() will call FreeGlyph() on an
|
||||||
|
already freed glyph, as reported by ASan:

||||||

SUMMARY: AddressSanitizer: heap-use-after-free xserver/render/glyph.c:252 in FreeGlyph
|
||||||
|
|
||||||
|
To avoid that, make sure not to free the given glyph in AddGlyph().
|
||||||
|
|
||||||
|
v2: Simplify the test using the boolean returned from AddGlyph() (Michel)
|
||||||
|
v3: Simplify even more by not freeing the glyph in AddGlyph() (Peter)
|
||||||
|
|
||||||
|
Fixes: bdca6c3d1 - render: fix refcounting of glyphs during ProcRenderAddGlyphs
