FINAL RESULTS:

data/anacron-2.3/log.c:81:11:  [4] (format) vsnprintf:
  If format strings can be influenced by an attacker, they can be exploited,
  and note that sprintf variations do not always \0-terminate (CWE-134). Use
  a constant for the format specification.
    len = vsnprintf(msg, sizeof(msg), fmt, args);
data/anacron-2.3/log.c:83:2:  [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(msg + sizeof(msg) - sizeof(truncated), truncated);
data/anacron-2.3/readtab.c:137:5:  [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(er->assign, env_var);
data/anacron-2.3/readtab.c:139:5:  [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(er->assign + var_len + 1, value);
data/anacron-2.3/readtab.c:173:5:  [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).

  (CWE-120). Consider using snprintf, strcpy_s, or strlcpy (warning: strncpy
  easily misused).
    strcpy(jr->command, command);
data/anacron-2.3/readtab.c:221:5:  [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(jr->ident, ident);
data/anacron-2.3/readtab.c:224:5:  [4] (buffer) strcpy:

  (CWE-120). Consider using snprintf, strcpy_s, or strlcpy (warning: strncpy
  easily misused).
    strcpy(jr->command, command);
data/anacron-2.3/runjob.c:124:5:  [4] (shell) execl:
  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.
    execl("/bin/sh", "/bin/sh", "-c", jr->command, (char *)NULL);
data/anacron-2.3/runjob.c:183:2:  [4] (shell) execl:

  (CWE-78). try using a library call that implements the same functionality
  if available.
	execl(SENDMAIL, SENDMAIL, "-FAnacron", "-odi",
data/anacron-2.3/main.c:109:19:  [3] (buffer) getopt:
  Some older implementations do not protect against internal buffer overflows
  (CWE-120, CWE-20). Check implementation on installation, or limit the size
  of all string inputs.
    while ((opt = getopt(argc, argv, "sfundqt:TS:Vh")) != EOF)

data/anacron-2.3/runjob.c:229:14:  [3] (buffer) getenv:
  Environment variables are untrustable input if they can be set by an
  attacker. They can have any content and length, and the same variable can
  be set more than once (CWE-807, CWE-20). Check environment variables
  carefully before using them.

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

data/anacron-2.3/lock.c:82:5:  [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.

  contents? (CWE-362).
    tab = fopen(anacrontab, "r");
data/anacron-2.3/runjob.c:54:7:  [2] (misc) open:
