FINAL RESULTS:

data/kalarm-20.08.2/src/functions.cpp:1752:5:  [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(timeStr, timeString.left(i >= 0 ? i : MAX_DT_LEN).constData());
data/kalarm-20.08.2/src/kamail.cpp:203:22:  [4] (shell) popen:
  This causes a new program to execute and is difficult to use safely
  (CWE-78). try using a library call that implements the same functionality
  if available.
        FILE* fd = ::popen(command.toLocal8Bit().constData(), "w");
data/kalarm-20.08.2/src/lib/shellprocess.cpp:198:18:  [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.
            &&  !access(envshell.data(), X_OK))         // and it's executable
