<P> Most bugs arise from mistakes and errors made in either a program 's source code or its design , or in components and operating systems used by such programs . A few are caused by compilers producing incorrect code . A program that contains a large number of bugs , and / or bugs that seriously interfere with its functionality , is said to be buggy ( defective ) . Bugs can trigger errors that may have ripple effects . Bugs may have subtle effects or cause the program to crash or freeze the computer . Other bugs qualify as security bugs and might , for example , enable a malicious user to bypass access controls in order to obtain unauthorized privileges . </P>
