| Summary | Multiple array index errors in programs that are automatically generated by VBox/HostServices/SharedOpenGL/crserverlib/server_dispatch.py in Oracle VirtualBox 4.2.x through 4.2.20 and 4.3.x before 4.3.8, when using 3D Acceleration, allow local guest OS users to execute arbitrary code on the Chromium server via certain CR_MESSAGE_OPCODES messages with a crafted index, which are not properly handled by the (1) CR_VERTEXATTRIB4NUBARB_OPCODE to the crServerDispatchVertexAttrib4NubARB function, (2) CR_VERTEXATTRIB1DARB_OPCODE to the crServerDispatchVertexAttrib1dARB function, (3) CR_VERTEXATTRIB1FARB_OPCODE to the crServerDispatchVertexAttrib1fARB function, (4) CR_VERTEXATTRIB1SARB_OPCODE to the crServerDispatchVertexAttrib1sARB function, (5) CR_VERTEXATTRIB2DARB_OPCODE to the crServerDispatchVertexAttrib2dARB function, (6) CR_VERTEXATTRIB2FARB_OPCODE to the crServerDispatchVertexAttrib2fARB function, (7) CR_VERTEXATTRIB2SARB_OPCODE to the crServerDispatchVertexAttrib2sARB function, (8) CR_VERTEXATTRIB3DARB_OPCODE to the crServerDispatchVertexAttrib3dARB function, (9) CR_VERTEXATTRIB3FARB_OPCODE to the crServerDispatchVertexAttrib3fARB function, (10) CR_VERTEXATTRIB3SARB_OPCODE to the crServerDispatchVertexAttrib3sARB function, (11) CR_VERTEXATTRIB4DARB_OPCODE to the crServerDispatchVertexAttrib4dARB function, (12) CR_VERTEXATTRIB4FARB_OPCODE to the crServerDispatchVertexAttrib4fARB function, and (13) CR_VERTEXATTRIB4SARB_OPCODE to the crServerDispatchVertexAttrib4sARB function. |

| Title | Oracle VirtualBox における任意のコードを実行される脆弱性 |
|---|---|
| Summary | Oracle VirtualBox の VBox/HostServices/SharedOpenGL/crserverlib/server_dispatch.py によって自動生成されるプログラムには、3D アクセラレーションを使用する場合、配列のインデックスエラーにより、Chromium サーバ上で任意のコードを実行される脆弱性が存在します。 |
| Possible impacts | ローカルのゲスト OS ユーザにより、巧妙に細工されたインデックスを持つ特定の CR_MESSAGE_OPCODES メッセージを介して、下記の項目によって適切に処理されないことで、Chromium サーバ上で任意のコードを実行される可能性があります。 (1) crServerDispatchVertexAttrib4NubARB 関数の CR_VERTEXATTRIB4NUBARB_OPCODE (2) crServerDispatchVertexAttrib1dARB 関数の CR_VERTEXATTRIB1DARB_OPCODE (3) crServerDispatchVertexAttrib1fARB 関数の CR_VERTEXATTRIB1FARB_OPCODE (4) crServerDispatchVertexAttrib1sARB 関数の CR_VERTEXATTRIB1SARB_OPCODE (5) crServerDispatchVertexAttrib2dARB 関数の CR_VERTEXATTRIB2DARB_OPCODE (6) crServerDispatchVertexAttrib2fARB 関数の CR_VERTEXATTRIB2FARB_OPCODE (7) crServerDispatchVertexAttrib2sARB 関数の CR_VERTEXATTRIB2SARB_OPCODE (8) crServerDispatchVertexAttrib3dARB 関数の CR_VERTEXATTRIB3DARB_OPCODE (9) crServerDispatchVertexAttrib3fARB 関数の CR_VERTEXATTRIB3FARB_OPCODE (10) crServerDispatchVertexAttrib3sARB 関数の CR_VERTEXATTRIB3SARB_OPCODE (11) crServerDispatchVertexAttrib4dARB 関数の CR_VERTEXATTRIB4DARB_OPCODE (12) crServerDispatchVertexAttrib4fARB 関数の CR_VERTEXATTRIB4FARB_OPCODE (13) crServerDispatchVertexAttrib4sARB 関数の CR_VERTEXATTRIB4SARB_OPCODE |
