Descriptions

The GLX extension in XFree86 4.0, X.Org X Window System (aka X11 or X) X11R6.7, and X.Org Server (aka xserver and xorg-server) before 1.16.3 allows remote authenticated users to cause a denial of service (out-of-bounds read or write) or possibly execute arbitrary code via a crafted length or index value to the (1) __glXDisp_Render, (2) __glXDisp_RenderLarge, (3) __glXDispSwap_VendorPrivate, (4) __glXDispSwap_VendorPrivateWithReply, (5) set_client_info, (6) __glXDispSwap_SetClientInfoARB, (7) DoSwapInterval, (8) DoGetProgramString, (9) DoGetString, (10) __glXDispSwap_RenderMode, (11) __glXDisp_GetCompressedTexImage, (12) __glXDispSwap_GetCompressedTexImage, (13) __glXDisp_FeedbackBuffer, (14) __glXDispSwap_FeedbackBuffer, (15) __glXDisp_SelectBuffer, (16) __glXDispSwap_SelectBuffer, (17) __glXDisp_Flush, (18) __glXDispSwap_Flush, (19) __glXDisp_Finish, (20) __glXDispSwap_Finish, (21) __glXDisp_ReadPixels, (22) __glXDispSwap_ReadPixels, (23) __glXDisp_GetTexImage, (24) __glXDispSwap_GetTexImage, (25) __glXDisp_GetPolygonStipple, (26) __glXDispSwap_GetPolygonStipple, (27) __glXDisp_GetSeparableFilter, (28) __glXDisp_GetSeparableFilterEXT, (29) __glXDisp_GetConvolutionFilter, (30) __glXDisp_GetConvolutionFilterEXT, (31) __glXDisp_GetHistogram, (32) __glXDisp_GetHistogramEXT, (33) __glXDisp_GetMinmax, (34) __glXDisp_GetMinmaxEXT, (35) __glXDisp_GetColorTable, (36) __glXDisp_GetColorTableSGI, (37) GetSeparableFilter, (38) GetConvolutionFilter, (39) GetHistogram, (40) GetMinmax, or (41) GetColorTable function.

La extensión GLX en XFree86 4.0, X.Org X Window System (también conocido como X11 o X) X11R6.7 y X.Org Server (también conocido como xserver y xorg-server) en versiones anteriores a 1.16.3 permite a usuarios remotos autenticados causar una denegación de servicio (lectura o escritura fuera de rango) o posiblemente ejecutar código arbitrario a través de un valor de longitud o índice manipulado a la función (1) __glXDisp_Render, (2) __glXDisp_RenderLarge, (3) __glXDispSwap_VendorPrivate, (4) __glXDispSwap_VendorPrivateWithReply, (5) set_client_info, (6) __glXDispSwap_SetClientInfoARB, (7) DoSwapInterval, (8) DoGetProgramString, (9) DoGetString, (10) __glXDispSwap_RenderMode, (11) __glXDisp_GetCompressedTexImage, (12) __glXDispSwap_GetCompressedTexImage, (13) __glXDisp_FeedbackBuffer, (14) __glXDispSwap_FeedbackBuffer, (15) __glXDisp_SelectBuffer, (16) __glXDispSwap_SelectBuffer, (17) __glXDisp_Flush, (18) __glXDispSwap_Flush, (19) __glXDisp_Finish, (20) __glXDispSwap_Finish, (21) __glXDisp_ReadPixels, (22) __glXDispSwap_ReadPixels, (23) __glXDisp_GetTexImage, (24) __glXDispSwap_GetTexImage, (25) __glXDisp_GetPolygonStipple, (26) __glXDispSwap_GetPolygonStipple, (27) __glXDisp_GetSeparableFilter, (28) __glXDisp_GetSeparableFilterEXT, (29) __glXDisp_GetConvolutionFilter, (30) __glXDisp_GetConvolutionFilterEXT, (31) __glXDisp_GetHistogram, (32) __glXDisp_GetHistogramEXT, (33) __glXDisp_GetMinmax, (34) __glXDisp_GetMinmaxEXT, (35) __glXDisp_GetColorTable, (36) __glXDisp_GetColorTableSGI, (37) GetSeparableFilter, (38) GetConvolutionFilter, (39) GetHistogram, (40) GetMinmax o (41) GetColorTable.

Multiple out-of-bounds write flaws were found in the way the X.Org server calculated memory requirements for certain GLX extension requests. A malicious, authenticated client could use either of these flaws to crash the X.Org server or, potentially, execute arbitrary code with root privileges.
