cscope -- buffer overflow vulnerabilities

Description:

Jason Duell reports:

Cscope contains an alarming number of buffer overflow vulnerabilities. By a rough count, there are at least 48 places where we blindly sprintf() a file name into a fixed-length buffer of size PATHLEN without checking to see if the file's name is <= PATHLEN. We do similar things with environment variable values.
