snapping bug

Some time ago Apple reported an iOS 7.0.6 bug that caused a man-in-the-middle attack, and the source of the bug was the following: Static Osstatus Sslverifysignedserverkeyexchange (Sslcontext *ctx, bool Isrsa, Sslbuffer Signedparams, uint8_t *signature, UInt16 signaturelen) {Osstatus err; .. if (err = Sslhashsha1.update (hashctx, serverrandom))!= 0) Goto fail; if (err = Sslhashs

A lot of Linux users found that the Linux server connected to enter the user name after a wait to enter the password, time is too long, now small to share with you how to solve the problem of SSH landing problems, I hope you have some help.1, we usually log on to the Linux server, we need to enter the user name after the wait, this time because of different time and so on.2, in fact, this problem is caused by the configuration of SSH inside, only need us to change the normal fast landing.3, we e

A simple write file operation was written in the NDK today:FILE *FP = fopen ("/sdcard/test.txt","W");if(fp = =NULL) {LOGD ("OPEN TEST.

the function to return 1, the sample code is as followsint class::init (int output, int input) { //arg check if (output_) { return-1; } .....}In this case, the compiler has no errors at all, and can only rely on its own caution.4. Inheriting classes calling the base class function with the same nameThe basic instance code is as followsClass Base {public: int init (int output, int input);}; Class class:public Base {int init (int output, int input);}; int class::init (int

- About returnMemfreed; $}Note: The above is a modified codeThe Collect function was found to perform gclist.remove (*p); After this step, the back of the P->refcount,p->isarray and other information is all wrong, suddenly wake up,Because this step frees the P node and later reads the information about the P node, it causes an error to occur. The correct approach is to first read the P-node RefCount,IsArray, and then releases the Memptr pointer in P, and finally releases the P node. Th

Recently updated to the latest version of Unity3d, this issue was discovered when using Il2cpp to publish 64-bit iOS apps. It resulted in my original encrypted files can not be extracted, checked the day, fixed.1. Download the zip's original code on GitHub, Https://codeload.github.com/0xd4d/de4dot/zip/master2. Directly under the Unity3d project, compile, the compiler will directly overwrite the system's own zip.3. Modify the source file: ~/zip/compression/streams/streammanipulator.csFromBuffer_

line above has been shown, indicating that he may not have encountered an array end identifier. To view the size of an array definition:Char weight_string[7] = {0char price_string[3] = {0};The last end of the original weight_string array was assigned a space by me. Then he will always read the memory data stored behind this array and display it. The so-called "array out of bounds".Fortunately we just read the display, and did not overwrite this data!Now that he shows the second row of data, the
