Flawfinder version 2.0.10, (C) 2001-2019 David A. Wheeler. Number of rules (primarily dangerous function names) in C/C++ ruleset: 223 Examining data/rifiuti-20040505/src/rifiuti.c FINAL RESULTS: data/rifiuti-20040505/src/rifiuti.c:177:17: [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. while ((opt = getopt( argc, argv, "dt:f:")) != -1) { data/rifiuti-20040505/src/rifiuti.c:72:3: [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 fourbytes[4]; data/rifiuti-20040505/src/rifiuti.c:133:3: [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 fourbytes[4]; data/rifiuti-20040505/src/rifiuti.c:135:3: [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 delim[10]; data/rifiuti-20040505/src/rifiuti.c:136:3: [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 ascdeltime[26]; data/rifiuti-20040505/src/rifiuti.c:159:16: [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). info2_file = open( argv[argc-1], O_RDONLY, 0 ); data/rifiuti-20040505/src/rifiuti.c:206:7: [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( ascdeltime, "%02d/%02d/%02d %02d:%02d:%02d", mon, deltm->tm_mday, year, deltm->tm_hour, deltm->tm_min, deltm->tm_sec ); data/rifiuti-20040505/src/rifiuti.c:44:3: [1] (buffer) read: Check buffer boundaries if used in a loop including recursive loops (CWE-120, CWE-20). read( d, buf, nbytes ); data/rifiuti-20040505/src/rifiuti.c:156:3: [1] (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). Risk is low because the source is a constant character. strcpy( delim, "\t" ); data/rifiuti-20040505/src/rifiuti.c:180:9: [1] (buffer) strncpy: Easily used incorrectly; doesn't always \0-terminate or check for invalid pointers [MS-banned] (CWE-120). strncpy( delim, optarg, 10 ); ANALYSIS SUMMARY: Hits = 10 Lines analyzed = 218 in approximately 0.02 seconds (13828 lines/second) Physical Source Lines of Code (SLOC) = 136 Hits@level = [0] 8 [1] 3 [2] 6 [3] 1 [4] 0 [5] 0 Hits@level+ = [0+] 18 [1+] 10 [2+] 7 [3+] 1 [4+] 0 [5+] 0 Hits/KSLOC@level+ = [0+] 132.353 [1+] 73.5294 [2+] 51.4706 [3+] 7.35294 [4+] 0 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
