Multiple vulnerabilities have been identified in X.Org X11, which could be exploited by local attackers to obtain elevated privileges.
The first issue is due to a memory corruption error in the "ProcRenderAddGlyphs()" function within the Render extension, which could be exploited by malicious users to execute arbitrary commands with "root" privileges via a specially crafted X protocol request.
The second vulnerability is due to memory corruption errors in the "ProcDbeGetVisualInfo()" and "ProcDbeSwapBuffers()" functions within the DBE extension, which could be exploited by malicious users to execute arbitrary commands with "root" privileges via a specially crafted X protocol request.
