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/etherwake-1.09/ether-wake.c FINAL RESULTS: data/etherwake-1.09/ether-wake.c:186:3: [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(if_hwaddr.ifr_name, ifname); data/etherwake-1.09/ether-wake.c:240:2: [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(whereto.sa_data, ifname); data/etherwake-1.09/ether-wake.c:128:14: [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 ((c = getopt(argc, argv, "bDi:p:uvV")) != -1) data/etherwake-1.09/ether-wake.c:194:3: [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(outpack+6, if_hwaddr.ifr_hwaddr.sa_data, 6); data/etherwake-1.09/ether-wake.c:205:3: [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(outpack+pktsize, wol_passwd, wol_passwd_sz); data/etherwake-1.09/ether-wake.c:235:3: [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(whereto.sll_addr, outpack, ETH_ALEN); data/etherwake-1.09/ether-wake.c:316:3: [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(pkt, station_addr, 6); data/etherwake-1.09/ether-wake.c:317:2: [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(pkt+6, station_addr, 6); data/etherwake-1.09/ether-wake.c:326:3: [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(pkt+offset, station_addr, 6); data/etherwake-1.09/ether-wake.c:223:3: [1] (buffer) strncpy: Easily used incorrectly; doesn't always \0-terminate or check for invalid pointers [MS-banned] (CWE-120). strncpy(ifr.ifr_name, ifname, sizeof(ifr.ifr_name)); data/etherwake-1.09/ether-wake.c:370:2: [1] (buffer) strncpy: Easily used incorrectly; doesn't always \0-terminate or check for invalid pointers [MS-banned] (CWE-120). strncpy (sa.sa_data, interface, sizeof sa.sa_data); data/etherwake-1.09/ether-wake.c:372:2: [1] (buffer) strncpy: Easily used incorrectly; doesn't always \0-terminate or check for invalid pointers [MS-banned] (CWE-120). strncpy (sa.sa_data, interface, sizeof sa.sa_data); ANALYSIS SUMMARY: Hits = 12 Lines analyzed = 392 in approximately 0.03 seconds (13008 lines/second) Physical Source Lines of Code (SLOC) = 290 Hits@level = [0] 23 [1] 3 [2] 6 [3] 1 [4] 2 [5] 0 Hits@level+ = [0+] 35 [1+] 12 [2+] 9 [3+] 3 [4+] 2 [5+] 0 Hits/KSLOC@level+ = [0+] 120.69 [1+] 41.3793 [2+] 31.0345 [3+] 10.3448 [4+] 6.89655 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
