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.

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.

data/dune-common-2.7.0/dune/common/test/dynmatrixtest.cc:67:7: [1] (buffer) equal:
Function does not check the second iterator for over-read conditions

in favor of its safer alternatives provided since C++14. Consider using a
form of this function that checks the second iterator before potentially
overflowing it.
