What is NX Bit? Its a exploit mitigation technique which makes certain areas of memory non executable and makes an executable area, non w Ritable. Example:data, stack and heap segments is made non executable while the text segment is made non writable.

The general process is to call the __gi___fortify_fail function first, __gi___fortify_fail call the __libc_message function, __libc_message the last call Backtrace_and_maps and _ _gi_abort function, generate SIGABRT signal, and through __gi___libc_secure_getenv according to the system environment variables to decide whether to produce Coredump file, __gi_abort execution to the last Call _exit, program exit.On the origin of the name of Canary, I found an interesti

bypass capacitance is not a theoretical concept, but a regular use of practical methods, in the 50-60 's, the word has its own meaning, and now no longer used. An electron tube or transistor needs to be biased, which is the DC supply condition that determines the operating point. For example, the gate of the tube with respect to the cathode is often required to add a negative pressure, in order to work in a DC power, in the cathode to the ground conne

Before writing the article received a lot of praise, mainly to help everyone to learn the new ideas. Since the release of the first article, I began to prepare the second article, the final plan to start in 07v8, this article I can guarantee that you can learn a lot of ideas. Before want to prepare an example video, request a lot of manufacturers to authorize, but involved in the vulnerability information, the manufacturers are very rigorous, so the whole process does not have relevant practical

the Web application, the input and program are mixed into SQL commands to access the database. The SQL commands that the final web app sends to the background data are:Select * from users where username = ' admin ' and Password = ' admin1234 ' (this form)This SQL query requires the database to check each row in the user table to extract records for each username column that has the admin and password columns values of admin1234. If the condition after where in the database is satisfied. The app

Also note the last one of the default gateways for IPV4 (typically 1).4. Once again enter the 1 screen, as shown, the third number of the network IP to 3 of the yellow box number.5. Click the NAT setting to change the last number of the gateway IP to the last one seen o
