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)

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.

Subject: [PATCH] xkb: Fix buffer overflow in _XkbSetCompatMap()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The _XkbSetCompatMap() function attempts to resize the `sym_interpret`
buffer.
However, It didn't update its size properly. It updated `num_si` only,
without updating `size_si`.
This may lead to local privilege escalation if the server is run as root
or remote code execution (e.g. x11 over ssh).
