Number of rules (primarily dangerous function names) in C/C++ ruleset: 223 Examining data/iat-0.1.3/src/iat.c FINAL RESULTS: data/iat-0.1.3/src/iat.c:368:10: [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. for (c=getopt(argc, argv, OPTIONS_LIST); data/iat-0.1.3/src/iat.c:370:9: [3] (buffer) getopt: Some older implementations do not protect against internal buffer overflows (CWE-120, CWE-20).
