However, despite numerous fixes and\nmitigations, MIG issues persist and offer incredibly powerful exploit primitives. Part of the\nproblem is that MIG semantics are complicated and unintuitive and do not align well with the\nkernel's abstractions.\n\nConsider the MIG routine task_swap_mach_voucher():\n\n\troutine task_swap_mach_voucher(\n\t\t\ttask\t\t: task_t;\n\t\t\tnew_voucher\t: ipc_voucher_t;\n\t\tinout\told_voucher\t: ipc_voucher_t);\n\nHere's the (placeholder) implementation:\n\n\tkern_return_t\n\ttask_swap_mach_voucher(\n\t\ttask_t\t\t\ttask,\n\t\tipc_voucher_t\t\tnew_voucher,\n\t\tipc_voucher_t\t\t*in_out_old_voucher)\n\t{\n\t\tif (TASK_NULL == task)\n\t\t\treturn KERN_INVALID_TASK;\n\n\t\t*in_out_old_voucher = new_voucher;\n\t\treturn KERN_SUCCESS;\n\t}\n\nThe correctness of this implementation depends on exactly how MIG ownership semantics are defined\nfor each of these parameters.\n\nWhen dealing with Mach ports and out-of-line memory, ownership follows the traditional rules (the\nones violated by the bugs above):\n\n1. All Mach ports (except the first) passed as input parameters are owned by the service routine if\n and only if the service routine returns success. If the service routine returns failure then MIG\n will deallocate the ports.\n\n2. All out-of-line memory regions passed as input parameters are owned by the service routine if\n and only if the service routine returns success. If the service routine returns failure then MIG\n will deallocate all out-of-line memory.\n\nBut this is only part of the picture. There are more rules for other types of objects:\n\n3. All objects with defined MIG translations that are passed as input-only parameters are borrowed\n by the service routine. For reference-counted objects, this means that the service routine is\n not given a reference, and hence a reference must be added if the service routine intends to\n keep the object around.\n\n4. All objects with defined MIG translations that are returned in output parameters must be owned\n by the output parameter. For reference-counted objects, this means that output parameters\n consume a reference on the object.\n\nAnd most unintuitive of all:\n\n5. All objects with defined MIG translations that are passed as input in input-output parameters\n are owned (not borrowed!) by the service routine. This means that the service routine must\n consume the input object's reference.\n\nHaving defined MIG translations means that there is an automatic conversion defined between the\nobject type and its Mach port representation. A task port is one example of such a type: you can\nconvert a task port to the underlying task object using convert_port_to_task(), and you can convert\na task to its corresponding port using convert_task_to_port().\n\nGetting back to Mach vouchers, this is the MIG definition of ipc_voucher_t:\n\n\ttype ipc_voucher_t = mach_port_t\n\t\t\tintran: ipc_voucher_t convert_port_to_voucher(mach_port_t)\n\t\t\touttran: mach_port_t convert_voucher_to_port(ipc_voucher_t)\n\t\t\tdestructor: ipc_voucher_release(ipc_voucher_t)\n\t\t ;\n\nThis definition means that MIG will automatically convert the voucher port input parameters to\nipc_voucher_t objects using convert_port_to_voucher(), convert the ipc_voucher_t output parameters\ninto ports using convert_voucher_to_port(), and discard any extra references using\nipc_voucher_release(). Note that convert_port_to_voucher() produces a voucher reference without\nconsuming a port reference, while convert_voucher_to_port() consumes a voucher reference and\nproduces a port reference.\n\nTo confirm our understanding of the MIG semantics outlined above, we can look at the function\n_Xtask_swap_mach_voucher(), which is generated by MIG during the build process:\n\n\tmig_internal novalue _Xtask_swap_mach_voucher\n\t\t(mach_msg_header_t *InHeadP, mach_msg_header_t *OutHeadP)\n\t{\n\t...\n\t\tkern_return_t RetCode;\n\t\ttask_t task;\n\t\tipc_voucher_t new_voucher;\n\t\tipc_voucher_t old_voucher;\n\t...\n\t\ttask = convert_port_to_task(In0P->Head.msgh_request_port);\n\n\t\tnew_voucher = convert_port_to_voucher(In0P->new_voucher.name);\n\n\t\told_voucher = convert_port_to_voucher(In0P->old_voucher.name);\n\n\t\tRetCode = task_swap_mach_voucher(task, new_voucher, &old_voucher);\n\n\t\tipc_voucher_release(new_voucher);\n\n\t\ttask_deallocate(task);\n\n\t\tif (RetCode != KERN_SUCCESS) {\n\t\t\tMIG_RETURN_ERROR(OutP, RetCode);\n\t\t}\n\t...\n\t\tif (IP_VALID((ipc_port_t)In0P->old_voucher.name))\n\t\t\tipc_port_release_send((ipc_port_t)In0P->old_voucher.name);\n\n\t\tif (IP_VALID((ipc_port_t)In0P->new_voucher.name))\n\t\t\tipc_port_release_send((ipc_port_t)In0P->new_voucher.name);\n\t...\n\t\tOutP->old_voucher.name = (mach_port_t)convert_voucher_to_port(old_voucher);\n\n\t\tOutP->Head.msgh_bits |= MACH_MSGH_BITS_COMPLEX;\n\t\tOutP->Head.msgh_size = (mach_msg_size_t)(sizeof(Reply));\n\t\tOutP->msgh_body.msgh_descriptor_count = 1;\n\t}\n\nTracing where each of the references are going, we can deduce that:\n\n1. The new_voucher parameter is deallocated with ipc_voucher_release() after invoking the service\n routine, so it is not owned by task_swap_mach_voucher(). In other words,\n task_swap_mach_voucher() is not given a reference on new_voucher.\n\n2. The old_voucher parameter has a reference on it before it gets overwritten by\n task_swap_mach_voucher(), which means task_swap_mach_voucher() is being given a reference on the\n input value of old_voucher.\n\n3. The value returned by task_swap_mach_voucher() in old_voucher is passed to\n convert_voucher_to_port(), which consumes a reference on the voucher.

However, despite numerous fixes and\r\nmitigations, MIG issues persist and offer incredibly powerful exploit primitives. Part of the\r\nproblem is that MIG semantics are complicated and unintuitive and do not align well with the\r\nkernel's abstractions.\r\n\r\nConsider the MIG routine task_swap_mach_voucher():\r\n\r\n\troutine task_swap_mach_voucher(\r\n\t\t\ttask\t\t: task_t;\r\n\t\t\tnew_voucher\t: ipc_voucher_t;\r\n\t\tinout\told_voucher\t: ipc_voucher_t);\r\n\r\nHere's the (placeholder) implementation:\r\n\r\n\tkern_return_t\r\n\ttask_swap_mach_voucher(\r\n\t\ttask_t\t\t\ttask,\r\n\t\tipc_voucher_t\t\tnew_voucher,\r\n\t\tipc_voucher_t\t\t*in_out_old_voucher)\r\n\t{\r\n\t\tif (TASK_NULL == task)\r\n\t\t\treturn KERN_INVALID_TASK;\r\n\r\n\t\t*in_out_old_voucher = new_voucher;\r\n\t\treturn KERN_SUCCESS;\r\n\t}\r\n\r\nThe correctness of this implementation depends on exactly how MIG ownership semantics are defined\r\nfor each of these parameters.\r\n\r\nWhen dealing with Mach ports and out-of-line memory, ownership follows the traditional rules (the\r\nones violated by the bugs above):\r\n\r\n1. All Mach ports (except the first) passed as input parameters are owned by the service routine if\r\n and only if the service routine returns success. If the service routine returns failure then MIG\r\n will deallocate the ports.\r\n\r\n2. All out-of-line memory regions passed as input parameters are owned by the service routine if\r\n and only if the service routine returns success. If the service routine returns failure then MIG\r\n will deallocate all out-of-line memory.\r\n\r\nBut this is only part of the picture. There are more rules for other types of objects:\r\n\r\n3. All objects with defined MIG translations that are passed as input-only parameters are borrowed\r\n by the service routine. For reference-counted objects, this means that the service routine is\r\n not given a reference, and hence a reference must be added if the service routine intends to\r\n keep the object around.\r\n\r\n4. All objects with defined MIG translations that are returned in output parameters must be owned\r\n by the output parameter. For reference-counted objects, this means that output parameters\r\n consume a reference on the object.\r\n\r\nAnd most unintuitive of all:\r\n\r\n5. All objects with defined MIG translations that are passed as input in input-output parameters\r\n are owned (not borrowed!) by the service routine. This means that the service routine must\r\n consume the input object's reference.\r\n\r\nHaving defined MIG translations means that there is an automatic conversion defined between the\r\nobject type and its Mach port representation. A task port is one example of such a type: you can\r\nconvert a task port to the underlying task object using convert_port_to_task(), and you can convert\r\na task to its corresponding port using convert_task_to_port().\r\n\r\nGetting back to Mach vouchers, this is the MIG definition of ipc_voucher_t:\r\n\r\n\ttype ipc_voucher_t = mach_port_t\r\n\t\t\tintran: ipc_voucher_t convert_port_to_voucher(mach_port_t)\r\n\t\t\touttran: mach_port_t convert_voucher_to_port(ipc_voucher_t)\r\n\t\t\tdestructor: ipc_voucher_release(ipc_voucher_t)\r\n\t\t ;\r\n\r\nThis definition means that MIG will automatically convert the voucher port input parameters to\r\nipc_voucher_t objects using convert_port_to_voucher(), convert the ipc_voucher_t output parameters\r\ninto ports using convert_voucher_to_port(), and discard any extra references using\r\nipc_voucher_release(). Note that convert_port_to_voucher() produces a voucher reference without\r\nconsuming a port reference, while convert_voucher_to_port() consumes a voucher reference and\r\nproduces a port reference.\r\n\r\nTo confirm our understanding of the MIG semantics outlined above, we can look at the function\r\n_Xtask_swap_mach_voucher(), which is generated by MIG during the build process:\r\n\r\n\tmig_internal novalue _Xtask_swap_mach_voucher\r\n\t\t(mach_msg_header_t *InHeadP, mach_msg_header_t *OutHeadP)\r\n\t{\r\n\t...\r\n\t\tkern_return_t RetCode;\r\n\t\ttask_t task;\r\n\t\tipc_voucher_t new_voucher;\r\n\t\tipc_voucher_t old_voucher;\r\n\t...\r\n\t\ttask = convert_port_to_task(In0P->Head.msgh_request_port);\r\n\r\n\t\tnew_voucher = convert_port_to_voucher(In0P->new_voucher.name);\r\n\r\n\t\told_voucher = convert_port_to_voucher(In0P->old_voucher.name);\r\n\r\n\t\tRetCode = task_swap_mach_voucher(task, new_voucher, &old_voucher);\r\n\r\n\t\tipc_voucher_release(new_voucher);\r\n\r\n\t\ttask_deallocate(task);\r\n\r\n\t\tif (RetCode != KERN_SUCCESS) {\r\n\t\t\tMIG_RETURN_ERROR(OutP, RetCode);\r\n\t\t}\r\n\t...\r\n\t\tif (IP_VALID((ipc_port_t)In0P->old_voucher.name))\r\n\t\t\tipc_port_release_send((ipc_port_t)In0P->old_voucher.name);\r\n\r\n\t\tif (IP_VALID((ipc_port_t)In0P->new_voucher.name))\r\n\t\t\tipc_port_release_send((ipc_port_t)In0P->new_voucher.name);\r\n\t...\r\n\t\tOutP->old_voucher.name = (mach_port_t)convert_voucher_to_port(old_voucher);\r\n\r\n\t\tOutP->Head.msgh_bits |= MACH_MSGH_BITS_COMPLEX;\r\n\t\tOutP->Head.msgh_size = (mach_msg_size_t)(sizeof(Reply));\r\n\t\tOutP->msgh_body.msgh_descriptor_count = 1;\r\n\t}\r\n\r\nTracing where each of the references are going, we can deduce that:\r\n\r\n1. The new_voucher parameter is deallocated with ipc_voucher_release() after invoking the service\r\n routine, so it is not owned by task_swap_mach_voucher(). In other words,\r\n task_swap_mach_voucher() is not given a reference on new_voucher.\r\n\r\n2. The old_voucher parameter has a reference on it before it gets overwritten by\r\n task_swap_mach_voucher(), which means task_swap_mach_voucher() is being given a reference on the\r\n input value of old_voucher.\r\n\r\n3. The value returned by task_swap_mach_voucher() in old_voucher is passed to\r\n convert_voucher_to_port(), which consumes a reference on the voucher. Thus,\r\n task_swap_mach_voucher() is giving _Xtask_swap_mach_voucher() a reference on the output value of\r\n old_voucher.\r\n\r\nFinally, looking back at the implementation of task_swap_mach_voucher(), we can see that none of\r\nthese rules are being followed:\r\n\r\n\tkern_return_t\r\n\ttask_swap_mach_voucher(\r\n\t\ttask_t\t\t\ttask,\r\n\t\tipc_voucher_t\t\tnew_voucher,\r\n\t\tipc_voucher_t\t\t*in_out_old_voucher)\r\n\t{\r\n\t\tif (TASK_NULL == task)\r\n\t\t\treturn KERN_INVALID_TASK;\r\n\r\n\t\t*in_out_old_voucher = new_voucher;\r\n\t\treturn KERN_SUCCESS;\r\n\t}\r\n\r\nThis results in two separate reference counting issues:\r\n\r\n1. By overwriting the value of in_out_old_voucher without first releasing the reference, we are\r\n leaking a reference on the input value of old_voucher.\r\n\r\n2.

However, despite numerous fixes and\nmitigations, MIG issues persist and offer incredibly powerful exploit primitives. Part of the\nproblem is that MIG semantics are complicated and unintuitive and do not align well with the\nkernel's abstractions.\n\nConsider the MIG routine task_swap_mach_voucher():\n\n\troutine task_swap_mach_voucher(\n\t\t\ttask\t\t: task_t;\n\t\t\tnew_voucher\t: ipc_voucher_t;\n\t\tinout\told_voucher\t: ipc_voucher_t);\n\nHere's the (placeholder) implementation:\n\n\tkern_return_t\n\ttask_swap_mach_voucher(\n\t\ttask_t\t\t\ttask,\n\t\tipc_voucher_t\t\tnew_voucher,\n\t\tipc_voucher_t\t\t*in_out_old_voucher)\n\t{\n\t\tif (TASK_NULL == task)\n\t\t\treturn KERN_INVALID_TASK;\n\n\t\t*in_out_old_voucher = new_voucher;\n\t\treturn KERN_SUCCESS;\n\t}\n\nThe correctness of this implementation depends on exactly how MIG ownership semantics are defined\nfor each of these parameters.\n\nWhen dealing with Mach ports and out-of-line memory, ownership follows the traditional rules (the\nones violated by the bugs above):\n\n1. All Mach ports (except the first) passed as input parameters are owned by the service routine if\n and only if the service routine returns success. If the service routine returns failure then MIG\n will deallocate the ports.\n\n2. All out-of-line memory regions passed as input parameters are owned by the service routine if\n and only if the service routine returns success. If the service routine returns failure then MIG\n will deallocate all out-of-line memory.\n\nBut this is only part of the picture. There are more rules for other types of objects:\n\n3. All objects with defined MIG translations that are passed as input-only parameters are borrowed\n by the service routine. For reference-counted objects, this means that the service routine is\n not given a reference, and hence a reference must be added if the service routine intends to\n keep the object around.\n\n4. All objects with defined MIG translations that are returned in output parameters must be owned\n by the output parameter. For reference-counted objects, this means that output parameters\n consume a reference on the object.\n\nAnd most unintuitive of all:\n\n5. All objects with defined MIG translations that are passed as input in input-output parameters\n are owned (not borrowed!) by the service routine. This means that the service routine must\n consume the input object's reference.\n\nHaving defined MIG translations means that there is an automatic conversion defined between the\nobject type and its Mach port representation. A task port is one example of such a type: you can\nconvert a task port to the underlying task object using convert_port_to_task(), and you can convert\na task to its corresponding port using convert_task_to_port().\n\nGetting back to Mach vouchers, this is the MIG definition of ipc_voucher_t:\n\n\ttype ipc_voucher_t = mach_port_t\n\t\t\tintran: ipc_voucher_t convert_port_to_voucher(mach_port_t)\n\t\t\touttran: mach_port_t convert_voucher_to_port(ipc_voucher_t)\n\t\t\tdestructor: ipc_voucher_release(ipc_voucher_t)\n\t\t ;\n\nThis definition means that MIG will automatically convert the voucher port input parameters to\nipc_voucher_t objects using convert_port_to_voucher(), convert the ipc_voucher_t output parameters\ninto ports using convert_voucher_to_port(), and discard any extra references using\nipc_voucher_release(). Note that convert_port_to_voucher() produces a voucher reference without\nconsuming a port reference, while convert_voucher_to_port() consumes a voucher reference and\nproduces a port reference.\n\nTo confirm our understanding of the MIG semantics outlined above, we can look at the function\n_Xtask_swap_mach_voucher(), which is generated by MIG during the build process:\n\n\tmig_internal novalue _Xtask_swap_mach_voucher\n\t\t(mach_msg_header_t *InHeadP, mach_msg_header_t *OutHeadP)\n\t{\n\t...\n\t\tkern_return_t RetCode;\n\t\ttask_t task;\n\t\tipc_voucher_t new_voucher;\n\t\tipc_voucher_t old_voucher;\n\t...\n\t\ttask = convert_port_to_task(In0P->Head.msgh_request_port);\n\n\t\tnew_voucher = convert_port_to_voucher(In0P->new_voucher.name);\n\n\t\told_voucher = convert_port_to_voucher(In0P->old_voucher.name);\n\n\t\tRetCode = task_swap_mach_voucher(task, new_voucher, &old_voucher);\n\n\t\tipc_voucher_release(new_voucher);\n\n\t\ttask_deallocate(task);\n\n\t\tif (RetCode != KERN_SUCCESS) {\n\t\t\tMIG_RETURN_ERROR(OutP, RetCode);\n\t\t}\n\t...\n\t\tif (IP_VALID((ipc_port_t)In0P->old_voucher.name))\n\t\t\tipc_port_release_send((ipc_port_t)In0P->old_voucher.name);\n\n\t\tif (IP_VALID((ipc_port_t)In0P->new_voucher.name))\n\t\t\tipc_port_release_send((ipc_port_t)In0P->new_voucher.name);\n\t...\n\t\tOutP->old_voucher.name = (mach_port_t)convert_voucher_to_port(old_voucher);\n\n\t\tOutP->Head.msgh_bits |= MACH_MSGH_BITS_COMPLEX;\n\t\tOutP->Head.msgh_size = (mach_msg_size_t)(sizeof(Reply));\n\t\tOutP->msgh_body.msgh_descriptor_count = 1;\n\t}\n\nTracing where each of the references are going, we can deduce that:\n\n1. The new_voucher parameter is deallocated with ipc_voucher_release() after invoking the service\n routine, so it is not owned by task_swap_mach_voucher(). In other words,\n task_swap_mach_voucher() is not given a reference on new_voucher.\n\n2. The old_voucher parameter has a reference on it before it gets overwritten by\n task_swap_mach_voucher(), which means task_swap_mach_voucher() is being given a reference on the\n input value of old_voucher.\n\n3. The value returned by task_swap_mach_voucher() in old_voucher is passed to\n convert_voucher_to_port(), which consumes a reference on the voucher. Thus,\n task_swap_mach_voucher() is giving _Xtask_swap_mach_voucher() a reference on the output value of\n old_voucher.\n\nFinally, looking back at the implementation of task_swap_mach_voucher(), we can see that none of\nthese rules are being followed:\n\n\tkern_return_t\n\ttask_swap_mach_voucher(\n\t\ttask_t\t\t\ttask,\n\t\tipc_voucher_t\t\tnew_voucher,\n\t\tipc_voucher_t\t\t*in_out_old_voucher)\n\t{\n\t\tif (TASK_NULL == task)\n\t\t\treturn KERN_INVALID_TASK;\n\n\t\t*in_out_old_voucher = new_voucher;\n\t\treturn KERN_SUCCESS;\n\t}\n\nThis results in two separate reference counting issues:\n\n1. By overwriting the value of in_out_old_voucher without first releasing the reference, we are\n leaking a reference on the input value of old_voucher.\n\n2. By assigning the value of new_voucher to in_out_old_voucher without adding a reference, we are\n consuming a reference we don't own, leading to an over-release of new_voucher.\n\nNow, Apple has previously added a mitigation to make reference count leaks on Mach ports\nnon-exploitable by having the reference count saturate before it overflows. However, this\nmitigation is not relevant here because we're leaking a reference on the actual ipc_voucher_t, not\non the voucher port that represents the voucher. And looking at the implementation of\nipc_voucher_reference() and ipc_voucher_release() (as of macOS 10.13.6), it's clear that the\nvoucher reference count is tracked independently of the port reference count:\n\n\tvoid\n\tipc_voucher_reference(ipc_voucher_t voucher)\n\t{\n\t\tiv_refs_t refs;\n\n\t\tif (IPC_VOUCHER_NULL == voucher)\n\t\t\treturn;\n\n\t\trefs = iv_reference(voucher);\n\t\tassert(1 < refs);\n\t}\n\n\tvoid\n\tipc_voucher_release(ipc_voucher_t voucher)\n\t{\n\t\tif (IPC_VOUCHER_NULL != voucher)\n\t\t\tiv_release(voucher);\n\t}\n\n\tstatic inline iv_refs_t\n\tiv_reference(ipc_voucher_t iv)\n\t{\n\t\tiv_refs_t refs;\n\n\t\trefs = hw_atomic_add(&iv->iv_refs, 1);\n\t\treturn refs;\n\t}\n\n\tstatic inline void\n\tiv_release(ipc_voucher_t iv)\n\t{\n\t\tiv_refs_t refs;\n\n\t\tassert(0 < iv->iv_refs);\n\t\trefs = hw_atomic_sub(&iv->iv_refs, 1);\n\t\tif (0 == refs)\n\t\t\tiv_dealloc(iv, TRUE);\n\t}\n\n(The assert()s are not live on production builds.)\n\nThis vulnerability can be triggered without crossing any privilege/MACF checks, so it should be\nreachable within every process and every sandbox.\n\nOn iOS 11 and macOS 10.13, both the over-reference and over-release vulnerabilities can be\nindependently exploited to free an ipc_voucher_t while it is still in use. On these platforms these\nare incredibly powerful vulnerabilities, since they also let us receive a send right to a\nfreed-and-reallocated Mach port back in userspace. For some examples of why this is dangerous, see\nIan's thoughts in issue 941: <https://bugs.chromium.org/p/project-zero/issues/detail?id=941#c3>.\n\nAs of iOS 12 and macOS 10.14, the voucher reference count is checked for underflow and overflow,\nwhich does make the over-reference vulnerability non-exploitable. However, the over-release\nvulnerability is still fully exploitable, and probably can still be used as a single,\ndirect-to-kernel bug from any process.\n\nAdditionally, while this report is of a single bug, it should indicate a wider problem with the\ncomplexity of obeying MIG semantics. It might be worth reviewing other edge cases of MIG semantics\nnot covered by previous bugs.\n\n(There's a variant of the over-reference vulnerability in thread_swap_mach_voucher(), but it is no\nlonger exploitable as of iOS 12.)\n\nThis proof-of-concept demonstrates the vulnerability by creating a Mach voucher, saving a reference\nto it in the current thread's ith_voucher field via thread_set_mach_voucher(), decreasing the\nreference count back to 1 using task_swap_mach_voucher(), and then freeing the voucher by\ndeallocating the voucher port in userspace. This leaves a dangling pointer to the freed voucher's\nmemory in ith_voucher, which can subsequently be accessed with a call to thread_get_mach_voucher(),\ntriggering a panic.\n\nTested on macOS 10.13.6 (17G4015), macOS 10.14.2, and iOS 12.1 (16B92).\n#endif\n\n#include <assert.h>\n#include <mach/mach.h>\n#include <stdio.h>\n#include <unistd.h>\n\n// Stash the host port for create_voucher().\nmach_port_t host;\n\n/*\n * create_voucher\n *\n * Description:\n * \tCreate a Mach voucher.
