Examining data/i810switch-0.6.5/i810switch.c

FINAL RESULTS:

data/i810switch-0.6.5/i810switch.c:368:10:  [4] (shell) popen:
  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.
	pci_f = popen(CMD_LSPCI " -n", "r");
data/i810switch-0.6.5/i810switch.c:389:10:  [4] (shell) popen:
  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.
	pci_f = popen(lspcistr, "r");
data/i810switch-0.6.5/i810switch.c:386:3:  [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(p, chip, 9);
data/i810switch-0.6.5/i810switch.c:402:12:  [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).
	par.mem = open("/dev/mem", (crt+lcd == -2) ? O_RDONLY : O_RDWR);
