RESULTS: data/ssh-cron-1.03.00/daemon/daemonize.cc:7:9: [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(ipcFile.c_str(), F_OK) == 0) data/ssh-cron-1.03.00/options/loadconfigfile.cc:9:13: [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(configFile.c_str(), R_OK) != 0) data/ssh-cron-1.03.00/daemon/reload.cc:8:27: [3] (buffer) realpath: This function does not protect against buffer overflows, and some implementations can overflow internally (CWE-120/CWE-785!). Ensure that the destination buffer is at least of size MAXPATHLEN, andto protect against implementation problems, the input argument should also be checked to ensure it is no larger than MAXPATHLEN. unique_ptr<char> path(realpath(ArgConfig::instance()[0], 0)); data/ssh-cron-1.03.00/cron/childredirections.cc:10:5: [2] (misc) open: Check when opening files - can an attacker redirect it (via symlinks), force the opening of special file type (e.g., device files), move things around to create a race condition, control its ancestors, or change its contents?

Exception::open(in, path); data/ssh-cron-1.03.00/crondata/crondata.h:35:12: [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. static char const *const s_month[12]; data/ssh-cron-1.03.00/crondata/crondata.h:36:12: [2] (buffer) char: Statically-sized arrays can be improperly restricted, leading to potential overflows or other issues (CWE-119!/CWE-120).

Consider using snprintf, strcpy_s, or strlcpy (warning: strncpy easily misused). Risk is low because the source is a constant string. strcpy(buffer.get() + ipcFile.copy(buffer.get(), string::npos), "XXXXXX"); data/ssh-cron-1.03.00/daemon/createipcfile.cc:12:14: [2] (tmpfile) mkstemp: Potential for temporary file vulnerability in some circumstances. Some older Unix-like systems create temp files with permission to write by all by default, so be sure to set the umask to override this. Also, some older Unix systems might fail to use O_EXCL when opening the file, so make sure that O_EXCL is used by the library (CWE-377). int fd = mkstemp(buffer.get()); data/ssh-cron-1.03.00/daemon/daemon1.cc:12:16: [2] (misc) open: Check when opening files - can an attacker redirect it (via symlinks), force the opening of special file type (e.g., device files), move things around to create a race condition, control its ancestors, or change its contents?
