Examining data/oss-preserve-1.1/ossctl.c

FINAL RESULTS:

data/oss-preserve-1.1/ossctl.c:91:7:  [4] (format) printf:
  If format strings can be influenced by an attacker, they can be exploited
  (CWE-134). Use a constant for the format specification.
      printf (line_format, 'D', i, 0);
data/oss-preserve-1.1/ossctl.c:96:4:  [4] (format) printf:
  If format strings can be influenced by an attacker, they can be exploited
  (CWE-134). Use a constant for the format specification.
	  printf (line_format,
data/oss-preserve-1.1/ossctl.c:101:7:  [4] (format) printf:
  If format strings can be influenced by an attacker, they can be exploited
  (CWE-134). Use a constant for the format specification.
      printf (line_format, 'X', 0, 0);
data/oss-preserve-1.1/ossctl.c:153:10:  [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 name [32];
data/oss-preserve-1.1/ossctl.c:155:5:  [2] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf. Risk is low because the source has a constant maximum length.
    sprintf (name, "/dev/mixer");
data/oss-preserve-1.1/ossctl.c:157:5:  [2] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf. Risk is low because the source has a constant maximum length.
    sprintf (name, "/dev/mixer%u", i);
data/oss-preserve-1.1/ossctl.c:169:17:  [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? (CWE-362).
      int fd = (open (filename, O_RDONLY, 0));
data/oss-preserve-1.1/ossctl.c:253:8:  [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? (CWE-362).
