FINAL RESULTS:
data/leveldb-1.22/util/env_posix.cc:562:14: [4] (race) access:
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())
and try to open the file directly.
return ::access(filename.c_str(), F_OK) == 0;
data/leveldb-1.22/util/posix_logger.h:84:16: [4] (format) vsnprintf:
If format strings can be influenced by an attacker, they can be exploited,
and note that sprintf variations do not always \0-terminate (CWE-134). Use
a constant for the format specification.
std::vsnprintf(buffer + buffer_offset, buffer_size - buffer_offset,
data/leveldb-1.22/util/windows_logger.h:78:16: [4] (format) vsnprintf:
If format strings can be influenced by an attacker, they can be exploited,
and note that sprintf variations do not always \0-terminate (CWE-134). Use
a constant for the format specification.

data/leveldb-1.22/issues/issue320_test.cc:43:8: [3] (random) srand:

such as key and nonce creation (CWE-327). Use a more secure technique for
acquiring random values.
std::srand(0);
data/leveldb-1.22/util/env_posix.cc:660:28: [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.
const char* env = std::getenv("TEST_TMPDIR");
data/leveldb-1.22/util/env_windows.cc:581:23: [3] (buffer) getenv:

carefully before using them.
const char* env = getenv("TEST_TMPDIR");
data/leveldb-1.22/util/testharness.cc:41:25: [3] (buffer) getenv:
