A race condition occurs when multiple processes access and manipulate the same data concurrently, and the outcome of the execution depends on the particular order in which the access takes place. A race condition is of interest to a hacker when the race condition can be utilized to gain privileged system access. Consider the following code snippet which illustrates a race condition: if(access("/tmp/datafile",R_OK)==0){ fd=open("/tmp/datafile process(fd); close(fd); This code creates the temporary file /tmp/datafile and then opens it. The potential race condition occurs between the call to access() and the call Read More

Bitmap images are a map or a collection of individually colored, minute dots or pixels (picture elements) that are arrayed in a matrix or grid. Since each individual pixel is too small for the naked eye to perceive without the help of magnification, an array of these pixels forms a perceivably smooth graphic image. Resizing Bitmap Images The quality of a bitmap image depends mainly on its resolution, which is the number of dots or pixels per inch of space. Therefore, resizing bitmap images result in poorer image quality. Decreasing Read More
