Buffer overlow :computer security In a C program, we print the address of relevant variables and arrays and get the following: 0xbfffe7b8 i 0xbfffe7bc length 0xbfffe7c0 hash_ptr 0xbfffe7ce targetuid 0xbfffe7d5 userid 0xbfffe817 pw 0xbfffe858 t 0xbfffe899 hashhex 0xbfffe8da target 0xbfffe91b hash 0xbfffe95c buffer The program executes the following instruction: strcpy(pw, buffer); You want to exploit the buffer overflow vulnerability by putting in buffer a string aaaaaaaaaaaaa ... 0c0beacef8877bbf2416eb00f2b5dc96354e26dd1df5517320459b1236860f8c with the goal of putting the hash 0c0beacef8877bbf2416eb00f2b5dc96354e26dd1df5517320459b1236860f8c variable target. If you count offset as 0 for the first a, 1 for the second a, and so on, what should be the offset of 0, the first character of the hash? In other words, how many a's should you put before the first zero character? (You can give the answer in decimal or in hexadecimal, but please specify.)

Compliant/Noncompliant Solutions The following code segment was provided in Secure Coding Guidelines for Java SE: void readData() throws IOException{ BufferedReader br = new BufferedReader(new InputStreamReader( new FileInputStream("file"))); // Read from the file String data = br.readLine();} The code is presented as a noncompliant coding example. For this assignment, identify two compliant solutions that can be utilized to ensure the protection of sensitive data. Provide a detailed explanation of factors, which influence noncompliant code and specifically how your solutions are now compliant. Your explanation should be 2-3 pages in length. Submit the following components: Word document with appropriate program analysis for your compliant solutions and source code in the Word file. Submit your .java source code file(s). If more than 1 file, submit a zip file.

Develop a data type for a buffer in a text editor that implements the following API:public class BufferBuffer() create an empty buffervoid insert(char c) insert c at the cursor positionchar delete() delete and return the character at the cursorvoid left(int k) move the cursor k positions to the leftvoid right(int k) move the cursor k positions to the rightint size() number of characters in the bufferAPI for a text bufferHint : Use two stacks
C++ PLEASE!! Working on a project that is about word count with MapReduce, need a file manager class to take care of reading all txt file from a directory with giving path. The file manager class need to open the directory with the giving path which the user will input, then open the path and open all the txt files in that directory and break the text into single line and pass it to another class to do mapping. Please help with the file manager class!! Thank you!!
