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, ProcRenderAddGlyphs() may free a glyph, leading to a use-after-free scenario when the same glyph pointer is subsequently accessed. This flaw allows an authenticated attacker to execute arbitrary code on the system by sending a specially crafted request."}, {"lang": "es", "value": "Se encontr\u00f3 una vulnerabilidad de use-after-free en la funci\u00f3n ProcRenderAddGlyphs() de los servidores Xorg.

En consecuencia, ProcRenderAddGlyphs() puede liberar un glifo, lo que lleva a un escenario de use-after-free cuando posteriormente se accede al mismo puntero de glifo.
