NAME
pscan - Format string security checker for C source
code
SYNOPSIS
pscan [options] pscan is a
source code analysis tool which is designed to highlight
potentially dangerous uses of variadic functions such as "printf",
"syslog", etc.
DETAILS
The scan works by looking for a one of a list of problem functions, and applying the following rule:
IF the last parameter of the function is the format string,
AND the format string is NOT a static string,
THEN complain.
LIMITATIONS
The code will not report on some potention buffer overflows, because that is not its goal. For example the following code is potential dangerous:
sprintf( static_buffer, "%s/.foorc", getenv("HOME") );
This code could cause an issue as there is no immediately obvious bounds checking. However this is a safe usages with regards to format strings.
RETURN VALUES
If there are any errors found, pscan exits with status 1.
