FINAL RESULTS:
data/mrd6-0.9.6/src/console/unix_console.cpp:49:6: [5] (race) chown:
This accepts filename arguments; if an attacker can move those files, a
race condition results. (CWE-362). Use fchown( ) instead.

If format strings can be influenced by an attacker, they can be exploited
(CWE-134). Use a constant for the format specification.
base_stream &printf(const char *, ...);
data/mrd6-0.9.6/src/console/console.cpp:152:3: [4] (buffer) strcpy:
Does not check for buffer overflows when copying to destination [MS-banned]
(CWE-120). Consider using snprintf, strcpy_s, or strlcpy (warning: strncpy
easily misused).

This usually indicates a security flaw. If an attacker can change anything
along the path between the call to access() and the file's actual use
(e.g., by moving files), the attacker can exploit the race condition
(CWE-362/CWE-367!). Set up the correct permissions (e.g., using setuid())

data/mrd6-0.9.6/src/main.cpp:56:14: [3] (buffer) getopt_long:
Some older implementations do not protect against internal buffer overflows
(CWE-120, CWE-20). Check implementation on installation, or limit the size
of all string inputs.
