CVE-2024-31083 Information

Description

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 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.
