Description Agostino Sarubbo gentoo-dev 2014-03-21 16:41:59 UTC
From ${URL} :


Core Security has reported multiple vulnerabilities in Oracle VirtualBox, which can be exploited by 
malicious, local users in a guest virtual machine to gain escalated privileges.

1) An error within the "crNetRecvReadback()" function (src/VBox/GuestHost/OpenGL/util/net.c) can be 
exploited to overwrite arbitrary hypervisor memory contents.

2) Two errors within the "crNetRecvReadback()" and "crNetRecvWriteback()" functions 
(src/VBox/GuestHost/OpenGL/util/net.c) can be exploited to manipulate arbitrary hypervisor memory 

3) A boundary error within multiple generated "crServerDispatchVertexAttrib*ARB()" functions 
(src/VBox/HostServices/SharedOpenGL/crserverlib/ can be exploited to cause a buffer 

Successful exploitation of these vulnerabilities may allow execution of arbitrary code with hypervisor 

The vulnerabilities are reported in versions 4.2.20 and 4.3.6. Other versions may also be affected.

Update to version 4.3.8.

Francisco Falcon, Core Exploit Writers Team.

CVE-2014-0983 (
  Multiple array index errors in programs that are automatically generated by
  VBox/HostServices/SharedOpenGL/crserverlib/ 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

CVE-2014-0981 (
  VBox/GuestHost/OpenGL/util/net.c in Oracle VirtualBox before 3.2.22, 4.0.x
  before 4.0.24, 4.1.x before 4.1.32, 4.2.x before 4.2.24, and 4.3.x before
  4.3.8, when using 3D Acceleration allows local guest OS users to execute
  arbitrary code on the Chromium server via crafted Chromium network pointer
  in a (1) CR_MESSAGE_READBACK or (2) CR_MESSAGE_WRITEBACK message to the
  VBoxSharedCrOpenGL service, which triggers an arbitrary pointer dereference
  and memory corruption.  NOTE: this issue was MERGED with CVE-2014-0982
  because it is the same type of vulnerability affecting the same set of
  versions. All CVE users should reference CVE-2014-0981 instead of

=app-emulation/virtualbox-4.3.8 hit tree via

Current stable version in tree is =app-emulation/virtualbox-4.3.38 and no vulnerable version left. So all done.

Added to existing GLSA.
