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/lomoco-1.0.0/src/cmdline.c Examining data/lomoco-1.0.0/src/cmdline.h Examining data/lomoco-1.0.0/src/lomoco.c Examining data/lomoco-1.0.0/src/lomoco.h FINAL RESULTS: data/lomoco-1.0.0/src/lomoco.c:84:11: [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 buf[12] = {0}; data/lomoco-1.0.0/src/lomoco.c:222:11: [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 buf[4] = {0}; data/lomoco-1.0.0/src/lomoco.c:258:11: [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 buf[4] = {0}; data/lomoco-1.0.0/src/lomoco.c:294:2: [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 buf[4] = {0}; data/lomoco-1.0.0/src/lomoco.c:297:12: [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). if ((fd = open(usbhid_mousepoll, O_RDONLY)) != -1) { data/lomoco-1.0.0/src/lomoco.c:299:16: [2] (integer) atoi: Unless checked, the resulting number can exceed the expected range (CWE-190). If source untrusted, check both minimum and maximum, even if the input had no minus sign (large numbers can roll over into negative number; consider saving to an unsigned value if that is intended). mousepoll = atoi (buf); data/lomoco-1.0.0/src/lomoco.c:616:2: [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 product[128]; data/lomoco-1.0.0/src/cmdline.c:173:8: [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). (strlen (arg) != 3) || data/lomoco-1.0.0/src/cmdline.c:188:8: [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). (strlen (arg) != 3) || data/lomoco-1.0.0/src/lomoco.c:298:8: [1] (buffer) read: Check buffer boundaries if used in a loop including recursive loops (CWE-120, CWE-20). if ((read (fd, buf, (sizeof(buf) - 1))) < (sizeof(buf) - 1)) ANALYSIS SUMMARY: Hits = 10 Lines analyzed = 1227 in approximately 0.07 seconds (17329 lines/second) Physical Source Lines of Code (SLOC) = 691 Hits@level = [0] 85 [1] 3 [2] 7 [3] 0 [4] 0 [5] 0 Hits@level+ = [0+] 95 [1+] 10 [2+] 7 [3+] 0 [4+] 0 [5+] 0 Hits/KSLOC@level+ = [0+] 137.482 [1+] 14.4718 [2+] 10.1302 [3+] 0 [4+] 0 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
