FINAL RESULTS:

data/muroar-0.1.13/muroar.c:267:15:  [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.
  if ( (len = readlink("/etc/roarserver", useraddr, sizeof(useraddr))) != -1 ) {
data/muroar-0.1.13/muroar.c:352:2:  [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((char*)&(buf[5]), name);
data/muroar-0.1.13/muroar.c:263:12:  [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.
  server = getenv("ROAR_SERVER");
data/muroar-0.1.13/muroar.c:296:10:  [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.
  home = getenv("HOME");
data/muroar-0.1.13/muroar.c:93:9:  [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 localnode[16] = {0};
data/muroar-0.1.13/muroar.c:194:2:  [2] (buffer) memcpy:
  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.
 memcpy((struct in_addr *)&(in.sin_addr), he->h_addr, sizeof(struct in_addr));
data/muroar-0.1.13/muroar.c:198:25:  [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).
  in.sin_port   = htons(atoi(object));
data/muroar-0.1.13/muroar.c:246:2:  [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.

  Statically-sized arrays can be improperly restricted, leading to potential

data/muroar-0.1.13/muroar_setvolume.c:29:11:  [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.
 unsigned char buf[20];
data/muroar-0.1.13/muroar_setvolume.c:30:11:  [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.
 unsigned char ans[10];
data/muroar-0.1.13/muroar_stream.c:30:11:  [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

data/muroar-0.1.13/muroarstream.c:68:9:  [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

  consider saving to an unsigned value if that is intended).
   bits = atoi(argv[++i]);
data/muroar-0.1.13/muroarstream.c:195:12:  [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).
  filefh = open(file, O_LARGEFILE|(tx ? O_RDONLY : O_WRONLY|O_CREAT|O_TRUNC), 0666);
data/muroar-0.1.13/muroar.c:114:4:  [1] (buffer) strncpy:
  Easily used incorrectly; doesn't always \0-terminate or check for invalid
  pointers [MS-banned] (CWE-120). Risk is low because the source is a
  constant string.
   strncpy(un.sun_path + 1, "RoarAudio/UNIX/Abstract/1", sizeof(un.sun_path) - 2);
data/muroar-0.1.13/muroar.c:116:4:  [1] (buffer) strncpy:

    strncpy(localnode, dp->n_name, sizeof(localnode)-1);
data/muroar-0.1.13/muroar.c:297:42:  [1] (buffer) strlen:
  Does not handle strings that are not \0-terminated; if given one it may
  perform an over-read (it could cause a crash if unprotected) (CWE-126).
  if ( home != NULL && home[0] == '/' && strlen(home) < (sizeof(useraddr) - 7) ) {
data/muroar-0.1.13/muroar.c:326:11:  [1] (buffer) strlen:
  Does not handle strings that are not \0-terminated; if given one it may
  perform an over-read (it could cause a crash if unprotected) (CWE-126).
