PScan is a C source code security scanner, which looks for misuse of
libc functions which use varargs and printf-style formatting
operators. In many situations these can cause security vulnerabilities
in the application if it runs with privileges (setugid, or listening
to a network socket, etc).
An example of the kind of situation pscan looks for is the following:
variable = "%s"; /* or malicious user input */
sprintf(buffer, variable); /* BAD! */
