+Subject: [PATCH xserver] 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:

+
+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 xserver 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.
+
+CVE-2024-31083, ZDI-CAN-22880
+
+This vulnerability was discovered by:
+Jan-Niklas Sohn working with Trend Micro Zero Day Initiative
