var-201904-1477
Vulnerability from variot
An input validation issue existed in the kernel. This issue was addressed with improved input validation. This issue affected versions prior to iOS 12, tvOS 12, watchOS 5. Both Apple iOS and tvOS are products of Apple Inc. in the United States. Apple iOS is an operating system developed for mobile devices. Kernel is one of the kernel components. tvOS is a smart TV operating system. An attacker can exploit this vulnerability to read restricted memory. iOS kernel stack memory disclosure due to failure to check copyin return value
CVE-2018-4363
Here's a code snippet from sleh.c with the second level exception handler for undefined instruction exceptions:
static void handle_uncategorized(arm_saved_state_t *state, boolean_t instrLen2) { exception_type_t exception = EXC_BAD_INSTRUCTION; mach_exception_data_type_t codes[2] = {EXC_ARM_UNDEFINED}; mach_msg_type_number_t numcodes = 2; uint32_t instr; <------ (a)
if (instrLen2) { uint16_t instr16; COPYIN(get_saved_state_pc(state), (char *)&instr16, sizeof(instr16));
instr = instr16;
} else { COPYIN(get_saved_state_pc(state), (char *)&instr, sizeof(instr)); <------- (b) }
....
else { codes[1] = instr; <------ (c) } }
exception_triage(exception, codes, numcodes); <-------- (d)
At (a) the uint32_t instr is declared uninitialized on the stack. At (b) the code tries to copyin the bytes of the exception-causing instruction from userspace note that the COPYIN macro doesn't itself check the return value of copyin, it just calls it. At (c) instr is assigned to codes[1], which at (d) is passed to exception_triage.
that codes array will eventually end up being sent in an exception mach message.
The bug is that we can force copyin to fail by unmapping the page containing the undefined instruction while it's being handled. (I tried to do this with XO memory but the kernel seems to be able to copyin that just fine.)
This PoC has an undefined instruction (0xdeadbeef) on its own page and spins up a thread to keep switching the protection of that page between VM_PROT_NONE and VM_PROT_READ|VM_PROT_EXECUTE.
We then keep spinning up threads which try to execute that undefined instruction.
If the race windows align the thread executes the undefined instruction but when the sleh code tries to copyin the page is unmapped, the copying fails and the exception message we get has stale stack memory.
This PoC just demonstrates that you do get values which aren't 0xdeadbeef in there for the EXC_ARM_UNDEFINED type. You'd have to do a bit more fiddling to work out how to get something specific there.
Note that there are lots of other unchecked COPYIN's in sleh.c (eg when userspace tries to access a system register not allowed for EL0) and these seem to have the same issue.
tested on iPod Touch 6g running 11.3.1, but looking at the kernelcache it seems to still be there in iOS 12.

This issue was addressed with improved input validation. This issue affected versions prior to iOS 12, tvOS 12, watchOS 5. Both Apple iOS and tvOS are products of Apple Inc. in the United States. Apple iOS is an operating system developed for mobile devices. Kernel is one of the kernel components. tvOS is a smart TV operating system. An attacker can exploit this vulnerability to read restricted memory. iOS kernel stack memory disclosure due to failure to check copyin return value \n\nCVE-2018-4363\n\n\nHere\u0027s a code snippet from sleh.c with the second level exception handler for undefined instruction exceptions:\n\n static void\n handle_uncategorized(arm_saved_state_t *state, boolean_t instrLen2)\n {\n exception_type_t exception = EXC_BAD_INSTRUCTION;\n mach_exception_data_type_t codes[2] = {EXC_ARM_UNDEFINED};\n mach_msg_type_number_t numcodes = 2;\n uint32_t instr; \u003c------ (a)\n \n if (instrLen2) {\n uint16_t instr16;\n COPYIN(get_saved_state_pc(state), (char *)\u0026instr16, sizeof(instr16));\n \n instr = instr16;\n } else {\n COPYIN(get_saved_state_pc(state), (char *)\u0026instr, sizeof(instr)); \u003c------- (b)\n }\n \n .... \n \n else {\n codes[1] = instr; \u003c------ (c)\n }\n }\n \n exception_triage(exception, codes, numcodes); \u003c-------- (d)\n \n \n At (a) the uint32_t instr is declared uninitialized on the stack. \n At (b) the code tries to copyin the bytes of the exception-causing instruction from userspace\n note that the COPYIN macro doesn\u0027t itself check the return value of copyin, it just calls it. \n At (c) instr is assigned to codes[1], which at (d) is passed to exception_triage. \n \n that codes array will eventually end up being sent in an exception mach message. \n \n The bug is that we can force copyin to fail by unmapping the page containing the undefined instruction\n while it\u0027s being handled. (I tried to do this with XO memory but the kernel seems to be able to copyin that just fine.)\n \n This PoC has an undefined instruction (0xdeadbeef) on its own page and spins up a thread to keep\n switching the protection of that page between VM_PROT_NONE and VM_PROT_READ|VM_PROT_EXECUTE. \n \n We then keep spinning up threads which try to execute that undefined instruction. \n \n If the race windows align the thread executes the undefined instruction but when the sleh code tries to copyin\n the page is unmapped, the copying fails and the exception message we get has stale stack memory. \n \n This PoC just demonstrates that you do get values which aren\u0027t 0xdeadbeef in there for the EXC_ARM_UNDEFINED type. \n You\u0027d have to do a bit more fiddling to work out how to get something specific there. \n \n Note that there are lots of other unchecked COPYIN\u0027s in sleh.c (eg when userspace tries to access a system register not allowed\n for EL0) and these seem to have the same issue. \n \n tested on iPod Touch 6g running 11.3.1, but looking at the kernelcache it seems to still be there in iOS 12. \n\n\n\nFound by: ianbeer\n\n. \nCVE-2018-4322: Min (Spark) Zheng, Xiaolong Bai of Alibaba Inc. \n\nBluetooth\nAvailable for: iPhone SE, iPhone 6s, iPhone 6s Plus, iPhone 7,\niPhone 7 Plus, iPad Mini 4, 12.9-inch iPad Pro 1st generation,\n12.9-inch iPad Pro 2nd generation, 10.5-inch iPad Pro,\n9.7-inch iPad Pro, iPad 5th generation, and iPod Touch 6th generation\nImpact: An attacker in a privileged network position may be able to\nintercept Bluetooth traffic\nDescription: An input validation issue existed in Bluetooth. \nCVE-2018-4329: Hugo S. \nCVE-2018-4338: Lee @ SECLAB, Yonsei University working with Trend\nMicro\u0027s Zero Day Initiative\n\nInstallation note:\n\nThis update is available through iTunes and Software Update on your\niOS device, and will not appear in your computer\u0027s Software Update\napplication, or in the Apple Downloads site.
