Fixes
Fixpack #2 (7/25/12)
xmc wildchild22 said:
Here is fixpack #2 to fix the sensors, auto rotations etc. The new boot.img also includes ramdisk edits to get closer at a fix for wifi. This is also included the latest compiled 3.0.3.6 kernel by TeamDS. (So this means button lights, proximity, and rotation.)
Thanks to Dillalade for early testing

I'm sorry. All I read in your post was the word bounty.
I can just see the Engadget article now...Sensational title, passive aggressive attitude towards Android, unfaltering praise for the developer, all by some idiot iPhone-toting glorified blogger. Yeah, that sounds just about right.
Anyway, does JB natively have support for hard keyboards?

I was able to get a logcat working...I'll post a download (non booting) later today. Now I'll be able to see why this rom isn't booting

What's the ETA on this? Haha just kidding!
I'm excited for this. I'd love some Jelly Bean on the MT4G Slide. If you need anybody to do some testing, I would be more than willing to help out!

You have come so far XMC.
Props dude.
Thanks for showing interest in the ever so smooth JellyBean

I was able to fix the error in recovery by using the ICS update-binary. I also had to change a little syntax for the wiping in the updater-script...no no more wrong permission errors in the logcat

Pre alpha released
Got this booting with a little building from source and porting expect DL tonight or tomorrow.

Wow, someone's on the move...

It's Holo Launcher. Also Apex is said to work.

Done Agent! XMC this is definitely newsworthy to us! And it deserves to be noticed by others as well. Any testing you need we're ready and willing!

Can't change font? (Crash)

Hello,
I got a One XL(Asia version), when i tired to change the default font on it, my phone won't work again.
I am just changing:
/system/fonts/DroidSans-Bold.ttf
/system/fonts/DroidSansFallback.ttf
My device are rooted, after replacing the file and doing backup, i tired to reboot, and the phone won't boot up again, it stuck on the "htc logo", adb still work, but the problem still exists when i copy the backup-ed file back to /system/fonts (via ADB), still, i can't get into the system.
I tired to logcat, and i find this:

This error keep raising, it seems that the system server died(?)
The only way to recover is flash my phone using RUU
Any solutions? I tired three time, and the error are SAME(lol i flashed my phone 3 times and i lost all apps and data..)

Anyone have this issue?

Just use font changer from the market.
I'm using windows phone 8 font, works great

[Q][GT-I9505][AOSP] stuck on android boot logo

I've compiled and flashed my SGS4 with the sources from: https://github.com/AOSP-S4/aosp_manifest
Found from: http://forum.xda-developers.com/showthread.php?t=2397511
The compilation was successful but i get stuck on the boot logo (/data /cache /dalvik wiped using cwm).

Evaluating CVE-2015-1474 to escalate to system privileges

I hope that with this thread we are able to gain system privileges with the help of CVE-2015-1474.
To begin with I try to write down what I have found. This is just a compilation of information so they might look mixed up.
The class GraphicBuffer is utilized by the system service SurfaceFlinger. My current understanding is that the vulnerable method "unflatten" is used to create a GraphicBuffer object from raw data that is sent to the service by IPC using Binder. A forged message might be easiest supplied via adb shell using this commando
Code:
[email protected]:/ $ service call SurfaceFlinger ...
I am not sure yet how the parcel get's eventually to the GraphicBuffer. It is a lot of code and I do not understand the low level graphics system of Android yet. The IGraphicBufferConsumer interface has a sub class BufferItem which has also an unflatten method which will call unflatten on GraphicBuffer. My gut tells me that the Parcel class is also involved in that process, but I'm not sure how yet.
One important piece of information that I'm still missing is how the unflattened data is used in the further processing of SurfaceFlinger. I don't think it is possible to freely write in the memory of SurfaceFlinger with this bug. There are still a lot of sanity checks to come by.
This could also effect on how we have to implement the communication with SurfaceFlinger. Maybe it's also possible with some forged objects and a SurfaceView.
Maybe together we are able to bring some light into this. A little bump in the right direction might help.

Take a look at the thread below, It looks like there is already some research begin done but I can't quite get my head around whether they are on the right track. This might help us get going in the right direction though.

Good news ( @Phate123, @awinston )! I have managed to crash the surfaceflinger on 4.5.2 (should also work on 4.5.3).
I'll upload the code on github, but first I want to briefly explain how I did it.
In Android everything that is a graphical element is represented by an GraphicBuffer.
GraphicBuffers are wrapped in BufferItems and managed by BufferQueues.
Each Queue has two sites, a producer side (IGraphicBufferProducer) and a consumer side (IGraphicBufferConsumer). In the basic scenario an app is the producer and the surfaceflinger is the consumer. These are obviously two different processes, but both must use the same BufferQueue.
BufferQueues are always created and owned by the consumers and consequently live in the same address space as the consumer. Producers must go through Binder to access their side of the queue.
As with everything in Android, the BufferQueue provides the same interface for both native (in the same process) and remote usage. The remote interface is implemented by a proxy that communicates through Binder with the other side.
In android KK BufferQueue implements the native side of the interface for both the producer (BnGraphicBufferProducer) and the consumer (BnGraphicBufferConsumer). These native implementations must provide a handler (onTransact) for requests that come from the remote proxies.
You can read more at https://source.android.com/devices/graphics/architecture.html.
Naturally, the first idea that comes into mind is to attack the native implementations of the BufferQueue that reside in the surfaceflinger. As the bug is in the unflatten routine of GraphicBuffer, we would like to craft a rogue parcel that represents a GraphicBuffer and then wait for the surfaceflinger to choke with it.
Unfortunately, from my findings, the bugged unflatten method is not called from the onTransact handler in the native implementations.
Only the proxy implementations seem to be a valid target, through BpGraphicBufferProducer::requestBuffer and BpGraphicBufferConsumer::aquireBuffer. Now we have a problem: as the BufferQueue resides in the surfaceflinger, there is no proxy implementation to attack.
Our only hope is to somehow create the BufferQueue in our process, so that we are the consumers, and use the surfaceflinger as the producer. This way the surfaceflinger would be accessing the BufferQueue through the bugged proxy (BpGraphicBufferProducer::requestBuffer). One way to use the surfaceflinger as a producer is to make screen captures.
I found the screencap command to be a very nice starting point to tinker with the idea as it does exactly what we wanted - it uses the surfaceflinger as a producer and pulls screen captures from it. Next I only had to hook the vtable entry of BpGraphicBufferProducer:: onTransact.
Now we have to control the overflow in GraphicsBuffer::unflatten.

Wow you are really good! I had started to piece some of this together and wanted to document it for good measure even though you are going to clearly beat the rest of us to this exploit. Arguably I could never figure it out, but never hurts to try. At least I am learning.

The screenshot test is where I was focusing but wasn't really getting very far.

Crashed unflatten as well
Okay so I crashed unflatten as well. Trying to figure out where to go from here. I am a little confused though because I did it natively by calling unflatten directly from a cpp program I wrote with a few lines of code. When you crash it like this how do I know it was the buffer overflow? Sorry, still trying to learn as I go.

Is the trick to do it through the surfaceflinger process because it is running with escalated privileges?

Is the trick to do it through the surfaceflinger process because it is running with escalated privileges?

Surfaceflinger runs under the system user (+drmrpc group) and should have access to /dev/qseecom, through which we can get root using CVE-2014-4322.
The problem is that the heap buffer overflow triggered by unflatten seems very difficult to exploit.
We must consider the following to achieve a controlled memory write:
sizeof(native_handle_t) + sizeof(int)*(numFds+numInts) must overflow 32 bits and remain small enough that the malloc succeeds and returns a valid heap address in h->data. If the malloc were to fail, we would memcpy to address 0 and get a seg fault.
as even after the malloc, numInts and numFds are used only after being multiplied by 4 (sizeof(int)), we can ignore the 2 most significant bits from both of them. This means that the only way to get any kind of bof is to generate transport from bit 29 to bit 30 on the sum numFds+numInts. Consequently, at least one of numInts or numFds must have bit 29 set. This doesn't sound very good because next we will do a memcpy of numFds * 4 bytes and next a memcpy of numInts * 4 bytes, meaning that at least one of the two memcpy calls will try to copy at least (1<<31) bytes. This will certainly lead to a segfault before we can trigger something from another thread...
the executable code is position independent so we would need to leak an address to be able to use rop.
Things don't look good at all... I really hope that I have made a mistake or that there is another approach to the problem.
I'm afraid that the pros would have already implemented an exploit by now, if it could have been done.

That have been my thoughts too. There is a memory corruption but it is difficult to use and it is not on areas that could be used to manipulate the return stack or a vtable entry. Or I just can't see the way. I have experience in this area,but it is kinda limited.
BTW: These drivers are not used by the Fire HDX by chance? https://www.codeaurora.org/projects...le-camera-drivers-cve-2014-4321-cve-2014-4324
Sadly I cannot find enough time to spend hours on digging. I hope there are some to be find this weekend though.

I don't think a stack attack would have been feasible at all as the code should be compiled with stack protector on and we can't do a brute force on the canary value. Hijacking a vtable pointer or a got entry would have been the way to go, but we still wouldn't know what to write as everything is aslr'd.
Regarding those camera drivers, I think someone over at the Samsung section also mentioned them. I'll look into them and report back.

Would you mind sharing your code even though it doesn't look like you will be able to exploit this overflow? I am still trying to get my head around the basic attack through surface flinger and it would help me greatly to better understand how at least in theory this works. No worries if you don't want to.

@jcase Says no on those camera group holes. http://forum.xda-developers.com/showpost.php?p=58945240&postcount=18
It's good to see other's working on 2015-1474 also :good:

@jcase is right, only mediaserver is executed under group camera so that it can access /dev/video*. You can see that in init.base.rc and ueventd.qcom.rc.
Now returning to the original topic... I fiddled around with unflatten, giving some input that should have made it crash.
What I did is I left numInts untouched and set numFds = -numInts. I was expecting surfaceflinger to crash every single time when it did the first memcpy. Somehow it didn't. I was baffled and had to gdb the process to see where my assumptions were wrong.
I breaked just before the first memcpy and printed the params:
Code:
(gdb) p $r0
$19 = 3074255348
(gdb) p $r1
$20 = 3074340312
(gdb) p $r2
$21 = 4294967248
r0 is the destination, r1 the source and r2 the number of bytes to copy. r2 is the unsigned representation of 4 * (-12) = 4 * numFds = -4 * numInts.
How did the program NOT crash???!! It even worked a second time, but crashed with SIGABRT in a free() because of heap corruption (I suppose). So even the second memcpy passed without segfault.
Here you have the memory map of surfaceflinger.
LE I have traced the memcpy. It looks like this on my Apollo 14.4.5.2
Code:
.text:0002218C __memcpy_base
.text:0002218C CMP R2, #4
.text:0002218E BLT.W loc_222DC
.text:00022192 CMP R2, #0x10
.text:00022194 BLT.W loc_222BE
.text:00022198 CMP R2, #0x20
.text:0002219A BLT.W loc_222AE
.text:0002219E CMP R2, #0x40
.text:000221A0 BLT loc_222A2
It seems like R2 (number of bytes) is treated like a signed int and the first branch is taken and the following instructions are executed
Code:
.text:000222DC loc_222DC ; CODE XREF: __memcpy_base+2
.text:000222DC LSLS R2, R2, #0x1F
.text:000222DE ITT CS
.text:000222E0 LDRCSH.W R3, [R1],#2
.text:000222E4 STRCSH.W R3, [R0],#2
.text:000222E8 ITT MI
.text:000222EA LDRMIB R3, [R1]
.text:000222EC STRMIB R3, [R0]
This ends up copying only n & 3 bytes, which is < 4. Basically, only the 2 least significant bits from n matter).
So... I guess we are able to write to h->data + numFds*4 as long as numFds*4 is negative. But having numFds as an offset may hurt us on the malloc side.
Now we have to defeat aslr somehow.

Any chance
I hope you are still working on this, we really need to get ride of the crappy Amazon OS and unlock the full potential of these amazing tablet specs.
I have an open tablet that I should repair, if there is need to take some photos of components please let me know, I am not into software hacking yet and it will takes me some time to get into it... but I want to contribute to make this possible, I hope more smart guys from around here join their effort to do it.
I wish if there is another tablet on the market who is as good as this one right now at an affordable price, to just see how CM12.1 behave on it, I tried it on a KFHD before I get it bricked it was fine but little bit laggy due to limited specs and low ram.

Hi, p1gl3t!
I'm interesting in your PoC and have to ask... Is your work on this done? And how might I use that for my specific device?

Not sure what this thread was all about (didn't look back) but the last post was over 2 years ago. A lot has happened since then; every 3rd gen HDX can be bootloader unlocked opening the door to custom ROMS ranging from Android 4.4.4 to 7.1.1.

Well, that's true but not for my device I still have a slightly outdated smartphone. It is Docomo Fujitsu Arrows NX F-01F [ Android 4.4.2, build # V10R22A (kernel version 3.4.0), ARMv7 arch (armv7l, armeabi-v7a) ]. And it's got no public firmwares at all, no bootloader unlock and no root in easy ways. Besides of that, there's one "pleasant" addition - PXN (Privilege Execute-Never), which doesn't let me to root the phone with simple ways or common tools.
To bypass PXN I have to use some JOP approach but for it I need to get boot.img or kernel memory dump somehow. Because I have no factory ROMs I'm trying to pull out boot.img through known vulnerabilities of my dev. One of them is CVE-2015-1474 (GraphicBuffer integer overflow), which potentially might give me system privilegies to copy boot.img from that phone.
So I wonder if p1gl3t's code is ready to use and is able to give the system privilegies. It seems it should be compiled together with AOSP codebase. But I'm unsure if it would work well when I get it compiled.
Checked your links. There I see that the presence of root is required. But I can't gain root so can't use those tools.

Have not seen @p1gl3t on this thread/forum in awhile; not sure if s/he is still active on XDA. Might try a PM. Given the age and, err, uniqueness of device in question I suspect you're in for quite a ride. Good luck.

Well, I have compiled that badscreencap by p1gl3t along with android 4.4.2 codebase and then pushed it to my dev. But whenever I run it I receive segfault:

Besides of the crash it seems to be incomplete because the code lacks any final ways of gaining elevated privileges (payload w/ reverse shell or something like that).
I assume it all makes no sense due to the loss of relevance for others. So I'll turn my attention to another CVE's out there. This could be the most elegant and shortest way of getting system though.

Is your goal to gain root on FireOS v3/v4/5 or are you experimenting with this for other reasons? If the former there are far easier methods (FireOS version dependent) of achieving this; even a theoretical way to unlock the bootloader sans root.

[Completed] RILD crash while Integrating ZTE 3G modem for Custom board with Android

Hello all,
We have ported Android 4.4 (kitkat) version on a custom board with iMX6 processor and are successful in getting Android running on the custom board. Now, when tried to add support for 3G modem provided by ZTE, the rild daemon is crashing continuously there disabling the complete telephony.
Android service for rild in init.rc file is as below
service ril-daemon /system/bin/rild -l /system/lib/libreference-ril.so -- -d /dev/ttyUSB2
class main
socket rild stream 660 root radio
socket rild-debug stream 660 radio system
user root
group radio cache inet misc audio
The sockets are getting created with the specified permissions as specified in the init.rc but unfortunately rild daemon is crashing throwing segmentation fault (SIGSEGV). The core dump of the crash
F/libc ( 2810): Fatal signal 11 (SIGSEGV) at 0x0000000c (code=1), thread 2821 (rild)

libc.so is not getting loaded but libc.so and libreference-ril-mw3820.so are all available in the system/lib folder. and the contents of system.prop is
rild.libpath=/system/lib/libreference-ril-mw3820.so
rild.libargs=-d /dev/ttyUSB2
but still the above crash persists. Any help on this would be of great help.
