FINAL RESULTS:

data/jattach-1.5/src/jattach_posix.c:50:25:  [5] (race) readlink:
  This accepts filename arguments; if an attacker can move those files or
  change the link content, a race condition results. Also, it does not
  terminate with ASCII NUL. (CWE-362, CWE-20). Reconsider approach.
    ssize_t path_size = readlink(path, temp_path_storage, sizeof(temp_path_storage) - 10);
data/jattach-1.5/src/jattach_windows.c:72:5:  [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(data.pipeName, pipeName);
data/jattach-1.5/src/jattach_windows.c:76:9:  [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(data.args[i], i < argc ? argv[i] : "");
data/jattach-1.5/src/jattach_posix.c:35:8:  [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 temp_path_storage[TMP_PATH] = {0};
data/jattach-1.5/src/jattach_posix.c:46:5:  [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.
    char path[64];
data/jattach-1.5/src/jattach_posix.c:51:5:  [2] (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). Risk is low because the source is a constant string.

data/jattach-1.5/src/jattach_posix.c:55:25:  [2] (misc) fopen:
  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? (CWE-362).
    FILE* status_file = fopen(path, "r");
data/jattach-1.5/src/jattach_posix.c:66:27:  [2] (integer) atoi:
  Unless checked, the resulting number can exceed the expected range
  (CWE-190). If source untrusted, check both minimum and maximum, even if the
  input had no minus sign (large numbers can roll over into negative number;
  consider saving to an unsigned value if that is intended).
            *uid = (uid_t)atoi(strchr(line + 5, '\t'));
data/jattach-1.5/src/jattach_posix.c:69:27:  [2] (integer) atoi:
