FINAL RESULTS:
data/cp2k-7.1/src/pw/fpga/opencl_utils.c:127:7: [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.
if( access( filename, R_OK ) != -1 ) {
data/cp2k-7.1/src/pw/fpga/opencl_utils.c:359:5: [4] (format) vprintf:
If format strings can be influenced by an attacker, they can be exploited
(CWE-134). Use a constant for the format specification.
vprintf(msg, vl);
data/cp2k-7.1/src/sockets.c:101:7: [4] (buffer) strcpy:
Does not check for buffer overflows when copying to destination [MS-banned]

easily misused).

data/cp2k-7.1/src/pw/fpga/fft_fpga.c:48:30: [2] (buffer) char:
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/cp2k-7.1/src/pw/fpga/fft_fpga.c:162:3: [2] (buffer) memcpy:

data/cp2k-7.1/src/sockets.c:81:7: [2] (buffer) sprintf:
