FINAL RESULTS:

data/mrc-1.2.3/mrc.cpp:786:11:  [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.
		int r = readlink("/proc/self/exe", exePath, PATH_MAX);
data/mrc-1.2.3/mrc.cpp:784:3:  [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 exePath[PATH_MAX + 1];
data/mrc-1.2.3/mrc.cpp:791:13:  [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(exePath, O_RDONLY);
data/mrc-1.2.3/mrc.cpp:794:14:  [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 e_ident[16];
data/mrc-1.2.3/mrc.cpp:79:8:  [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).
		p += strlen(p) + 1;
data/mrc-1.2.3/mrc.cpp:796:9:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
				if (read(fd, e_ident, sizeof(e_ident)) == sizeof(e_ident) and
data/mrc-1.2.3/mrc.cpp:811:12:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
							if (read(fd, &hdr, sizeof(hdr)) == sizeof(Elf32_Ehdr))
data/mrc-1.2.3/mrc.cpp:822:12:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
