data/siscone-2.0.6/examples/options.cpp:158:2: [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).
strcpy(ev_name, optarg);

(CWE-120, CWE-20). Check implementation on installation, or limit the size
of all string inputs.

data/siscone-2.0.6/examples/test.cpp:69:3: [3] (random) srand:
This function is not sufficiently random for security-related functions
such as key and nonce creation (CWE-327). Use a more secure technique for
acquiring random values.

around to create a race condition, control its ancestors, or change its
contents? (CWE-362).
