FINAL RESULTS:
data/findent-3.1.7/src/builtparser.cpp:1082:21: [4] (format) fprintf:
If format strings can be influenced by an attacker, they can be exploited
(CWE-134). Use a constant for the format specification.
# define YYFPRINTF fprintf
data/findent-3.1.7/src/flags.cpp:70:20: [3] (buffer) getenv:
Environment variables are untrustable input if they can be set by an
attacker. They can have any content and length, and the same variable can
be set more than once (CWE-807, CWE-20). Check environment variables
carefully before using them.

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.

Statically-sized arrays can be improperly restricted, leading to potential
overflows or other issues (CWE-119!/CWE-120). Perform bounds checking, use
functions that limit length, or ensure that the size is larger than the
maximum possible length.
