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
|
