xorg-x11-server: Use-after-free in ProcRenderAddGlyphs

A use-after-free vulnerability was found in the ProcRenderAddGlyphs function of Xorg servers. This issue occurs when AllocateGlyph is called to store new glyphs sent by the client to the X server, potentially resulting in multiple entries pointing to the same non-refcounted glyphs. Consequently,...
