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/quitcount-3.1.4/src/main.c FINAL RESULTS: data/quitcount-3.1.4/src/main.c:104:24: [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). stop_date = (time_t)atoi(*(++cur_var)); data/quitcount-3.1.4/src/main.c:106:18: [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). num_per_day = atoi(*(++cur_var)); data/quitcount-3.1.4/src/main.c:114:16: [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). pack_size = atoi(*(++cur_var)); ANALYSIS SUMMARY: Hits = 3 Lines analyzed = 793 in approximately 0.04 seconds (18007 lines/second) Physical Source Lines of Code (SLOC) = 649 Hits@level = [0] 2 [1] 0 [2] 3 [3] 0 [4] 0 [5] 0 Hits@level+ = [0+] 5 [1+] 3 [2+] 3 [3+] 0 [4+] 0 [5+] 0 Hits/KSLOC@level+ = [0+] 7.70416 [1+] 4.6225 [2+] 4.6225 [3+] 0 [4+] 0 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
