Ansi C patch using dlsym compiles OK under linux but fails on Mac Os X

阅读更多关于 Ansi C patch using dlsym compiles OK under linux but fails on Mac Os X

问题 I have build a little patch to append to a certain application and trace the invocations of some functions. Among them, malloc() and open(). I am using dlsym to store the pointer to the original symbol and replace the function name with my own. It compiles -and works- perfectly under linux. Here's the code: #define _GNU_SOURCE #include <stdint.h> #include <stdio.h> #include <string.h> #include <stdarg.h> #include <dlfcn.h> /** * Interponemos nuestra funcion open * * @param char* filename *

“Injection” concerns for Cypher over REST

阅读更多关于 “Injection” concerns for Cypher over REST

I was wondering if there is a concern for query injection when I query over REST? Parameterizing the query definitely makes things more cleaner but I was also able to query with string concatenation to manipulate properties and labels. I find the latter approach being more flexible because at times I can't query the way I want it following the paradigm of parameters. ( Can I parameterize labels and properties on CREATE or SET? (REST and transaction) ) If there is no worries of some sort of injection is it a security risk to concat query strings? I personally do not have too deep of an

GetModuleHandleA fails to get modules not used by python.exe when attached to another process

阅读更多关于 GetModuleHandleA fails to get modules not used by python.exe when attached to another process

I am working with Grey Hat Python book at the moment. It describes on how to create a debugger in python. So far my debugger is able to start the process and attach to it. The problem happens when I try to retrieve a module handle from the process. According to OllyDbg the DLL is present in the program, but GetModuleHandleA fails to get a handle. I improved a code from the book a little bit so in case GetModuleHandleA fails to retrieve a handle the function will try to create a remote thread and force to load this module into the process. But even so it GetModuleHandleA fails (while everything

Mockito injection not working for constructor AND setter mocks together

问题 I have a class that has members injected through constructors, and OTHERS through setters. I can't seem to get Mockito to inject the setter ones. The constructor-injected are mocked fine, but the setter ones come back as null. When I flipped the setter-ed members to constructor- injected, all is well. here is the original production code: @Autowired private BetRepository betRepository; public void setBetRepository(BetRepository betRepository) { this.betRepository = betRepository; } public

This question already has answers here : Closed 7 years ago . Possible Duplicate: Best way to prevent SQL injection in PHP? I have been doing some research about SQL Injection but I have some questions that I couldn't find answer to. Isn't it possible to prevent SQL injection attacks on string levels?
