A read of the data from one or more of the files resulted in more bytes being read than the read request stated. The end result is that the cpu started executing data instead of code. The causes of the problem could be that the program which reads the data does not check to see that no extra data was read or that the file which the computer was reading had been altered to add extraneous data, or both.
The danger to data execution is that malware writers are aware of programs which do not check the results of each read request. Hence, such writers create programs which alter ordinary files to insert malware into the target computers. Hence, DEP is a very good idea and should not be disabled.
