  • Printf in assembler doesn't print

    - by Gaim
    Hi there, I have got a homework to hack program using buffer overflow ( with disassambling, program was written in C++, I haven't got the source code ). I have already managed it but I have a problem. I have to print some message on the screen, so I found out address of printf function, pushed address of "HACKED" and address of "%s" on the stack ( in this order ) and called that function. Called code passed well but nothing had been printed. I have tried to simulate the environment like in other place in the program but there has to be something wrong. Do you have any idea what I am doing wrong that I have no output, please? Thanks a lot EDIT: This program is running on Windows XP SP3 32b, written in C++, Intel asm there is the "hack" code CPU Disasm Address Hex dump Command Comments 0012F9A3 90 NOP ;hack begins 0012F9A4 90 NOP 0012F9A5 90 NOP 0012F9A6 89E5 MOV EBP,ESP 0012F9A8 83EC 7F SUB ESP,7F ;creating a place for working data 0012F9AB 83EC 7F SUB ESP,7F 0012F9AE 31C0 XOR EAX,EAX 0012F9B0 50 PUSH EAX 0012F9B1 50 PUSH EAX 0012F9B2 50 PUSH EAX 0012F9B3 89E8 MOV EAX,EBP 0012F9B5 83E8 09 SUB EAX,9 0012F9B8 BA 1406EDFF MOV EDX,FFED0614 ;address to jump, it is negative because there mustn't be 00 bytes 0012F9BD F7DA NOT EDX 0012F9BF FFE2 JMP EDX ;I have to jump because there are some values overwritten by the program 0012F9C1 90 NOP 0012F9C2 0090 00000000 ADD BYTE PTR DS:[EAX],DL 0012F9C8 90 NOP 0012F9C9 90 NOP 0012F9CA 90 NOP 0012F9CB 90 NOP 0012F9CC 6C INS BYTE PTR ES:[EDI],DX ; I/O command 0012F9CD 65:6E OUTS DX,BYTE PTR GS:[ESI] ; I/O command 0012F9CF 67:74 68 JE SHORT 0012FA3A ; Superfluous address size prefix 0012F9D2 2069 73 AND BYTE PTR DS:[ECX+73],CH 0012F9D5 203439 AND BYTE PTR DS:[EDI+ECX],DH 0012F9D8 34 2C XOR AL,2C 0012F9DA 2066 69 AND BYTE PTR DS:[ESI+69],AH 0012F9DD 72 73 JB SHORT 0012FA52 0012F9DF 74 20 JE SHORT 0012FA01 0012F9E1 3120 XOR DWORD PTR DS:[EAX],ESP 0012F9E3 6C INS BYTE PTR ES:[EDI],DX ; I/O command 0012F9E4 696E 65 7300909 IMUL EBP,DWORD PTR DS:[ESI+65],-6F6FFF8D 0012F9EB 90 NOP 0012F9EC 90 NOP 0012F9ED 90 NOP 0012F9EE 31DB XOR EBX,EBX ; hack continues 0012F9F0 8818 MOV BYTE PTR DS:[EAX],BL ; writing 00 behind word "HACKED" 0012F9F2 83E8 06 SUB EAX,6 0012F9F5 50 PUSH EAX ; address of "HACKED" 0012F9F6 B8 3B8CBEFF MOV EAX,FFBE8C3B 0012F9FB F7D0 NOT EAX 0012F9FD 50 PUSH EAX ; address of "%s" 0012F9FE B8 FFE4BFFF MOV EAX,FFBFE4FF 0012FA03 F7D0 NOT EAX 0012FA05 FFD0 CALL EAX ;address of printf This code is really ugly because I am new in assembler and there mustn't be null bytes because of buffer-overflow bug

  • Need some guidelines on iPad animation programming

    - by thomasvsundert
    Hi, I'm creating an interactive e-book for the iPad. This book will contain multiple pages that will consist of a lot of animations (frame and motion animations), transitions,... I was wondering what my development options are, should I use OpenGL, Quartz,...? I've use UIImageView.animationImages before and found that it had really bad performance. What's the best way to draw frame based animations? Does anybody have some good pointers to resources on this? thanks in advance, Thomas

  • Charting library for Blackberry devices (native)

    - by dozerbull
    Does anyone know of a library to display charts and graphs natively on blackberry devices ? There are quite a few javascript (Flot...) charting libraries but I'd rather use something similar to Coreplot on iPhone if it is possible. I didn't find anything on top of SVG (JSR 226) or open GL ES (JSR 239) so any help is appreciated. Ideally, I'd like to be able to: draw Bar Charts (both vertical and horizontal) draw Stacked bar charts draw Pie charts drill-down one level on each bar or pie section to get corresponding information

  • Is there anyway to exclude artifacts inherited from a parent POM?

    - by Miguel
    Artifacts from dependencies can be excluded by declaring an <exclusions> element inside a <dependency> But in this case it's needed to exclude an artifact inherited from a parent project. An excerpt of the POM under discussion follows: <project> <modelVersion>4.0.0</modelVersion> <groupId>test</groupId> <artifactId>jruby</artifactId> <version>0.0.1-SNAPSHOT</version> <parent> <artifactId>base</artifactId> <groupId>es.uniovi.innova</groupId> <version>1.0.0</version> </parent> <dependencies> <dependency> <groupId>com.liferay.portal</groupId> <artifactId>ALL-DEPS</artifactId> <version>1.0</version> <scope>provided</scope> <type>pom</type> </dependency> </dependencies> </project> base artifact, depends on javax.mail:mail-1.4.jar, and ALL-DEPS depends on another version of the same library. Due to the fact that mail.jar from ALL-DEPS exist on the execution environment, although not exported, collides with the mail.jar that exists on the parent, which is scoped as compile. A solution could be to rid off mail.jar from the parent POM, but most of the projects that inherit base, need it (as is a transtive dependency for log4j). So What I would like to do is to simply exclude parent's library from the child project, as it could be done if base was a dependency and not the parent pom: ... <dependency> <artifactId>base</artifactId> <groupId>es.uniovi.innova</groupId> <version>1.0.0</version> <type>pom<type> <exclusions> <exclusion> <groupId>javax.mail</groupId> <artifactId>mail</artifactId> </exclusion> </exclusions> </dependency> ...

  • Insight into how things get printed onto the screen (cout,printf) and origin of really complex stuff

    - by sil3nt
    I've always wondered this, and still haven't found the answer. Whenever we use "cout" or "printf" how exactly is that printed on the screen?. How does the text come out as it does...(probably quite a vague question here, ill work with whatever you give me.). So basically how are those functions made?..is it assembly?, if so where does that begin?. This brings on more questions like how on earth have they made openGl/directx functions.. break it down people break it down.:)

  • Drawing translucent bitmaps using Canvas (Android)

    - by mcbitmap
    I have a Bitmap object and want to render it to a Canvas object with varying levels of translucency (i.e. make the whole bitmap partially see through). For example, I have sprites in a game (that are drawn over the top of a bitmap background) that I want to fade out from being opaque to being invisible. Can I do this without having to resort to OpenGL?

  • How to add values dynamically to I18n?

    - by Dima Goltsman
    I have many ymls in my rails app, and i want to put some of them in other service, so that i can call this from multiple places. the response of this call will be a hash. {"en" : {"test" : {"text1" : "hi english"}, {"text2" : "mambo number %{num}"} }, "es" : {"test" : {"text1" : "hi espaniol"}, {"text2" : "mamboes numeros %{num}"} } } is there a way i can load that hash into I18n translations like I18n.add_translations(some_hash) so i can access them with I18n.t("test.text1") I18n.t("test.text2", :num => 5) how can i achieve it?

    Hello, I am having some problems getting some French text to convert to UTF8 so that it can be displayed properly, either in a console, text file or in a GUI element. The original string is HANDICAP+ES which is supposed to be HANDICAPÉES No matter how I tried converting it, it appears the same way. Any ideas on how I can do this conversion? Thanks, Cam

  • C++ Win32 API equivalent of CultureInfo.TwoLetterISOLanguageName

    - by Brian Gillespie
    The .NET framework makes it easy to get information about various locales; the Win32 C++ APIs are a bit harder to figure out. Is there an equivalent function in Win32 to get the two-letter ISO language name given an integer locale ID? In C# I'd do: System.Globalization.CultureInfo ci = new System.Globalization.CultureInfo(1034); string iso = ci.TwoLetterISOLanguageName; // iso == "es" now.

  • Optimal pixel format for drawing on iPhone?

    - by Felixyz
    Pretty simple question: when doing some pretty intense drawing with CoreGraphics on the iPhone, how can I specify the pixel format to get optimal performance? Is the format that I get from the context via UIGraphicsGetCurrentContext per definition the best one? I know that RGB565 is supposed to be the fastest to use in OpenGL. Does that go for CoreGraphics as well? General advice?

  • MVC and conditional formatting - strategies for implementation

    - by Extrakun
    Right now I am writing a simulation program which output is formatted according to certain factors. The question is in a MVC architecture, where is the conditional formatting to be taken place? What are some strategies for implement this feature? FYI, The platform I am using is rather bare-bone in its GUI/front-end execution. To change color and formatting, it requires a change to the formatting state (much like OpenGL).

  • Can these sorts of programs exist in every Turing-complete language?

    - by I can't tell you my name.
    In every Turing-Complete language, is it possible to create a working Compiler for itself which first runs on an interpreter written in some other language and then compiles it's own source code? (Bootstrapping) Standards-Compilant C++ compiler which outputs binaries for, e.g.: Windows? Regex Parser and Evaluater? World of Warcraft clone? (Assuming the language gets the necessary API bindings as, for example, OpenGL and the WoW source code is available) (Everything here theoretical) Let's take Brainf*ck as an example language.

    How could I let a user jot a quick hand-written note on an iPad using a Pogo-like stylus? (Or by using their finger, some kind of stylus makes it more legible feasible.) Initial thoughts: 1) Open GL canvas? 2) Store the output as a .png/.jpg snapshot of the openGL screen (by taking a screenhot of the iPad? 3) Would the note be limited to one screenshot, could there be a scrollable area notepad to write out a long note?
