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/wmxres-1.4/wmxres.c FINAL RESULTS: data/wmxres-1.4/wmxres.c:29:1: [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 res_active[12]; data/wmxres-1.4/wmxres.c:30:1: [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 res_list[100][20]; data/wmxres-1.4/wmxres.c:170:3: [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(res_list[c], "%dx%d", res_modelines[c]->hdisplay, res_modelines[c]->vdisplay); data/wmxres-1.4/wmxres.c:183:2: [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(res_active, "%dx%d", vm_modelines.hdisplay, vm_modelines.vdisplay); data/wmxres-1.4/wmxres.c:209:1: [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[1024]; data/wmxres-1.4/wmxres.c:217:4: [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). k=atoi(res_width); data/wmxres-1.4/wmxres.c:218:2: [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(buf, "%04i", k); data/wmxres-1.4/wmxres.c:228:4: [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). k=atoi(res_height); data/wmxres-1.4/wmxres.c:229:2: [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(buf, "%04i", k); ANALYSIS SUMMARY: Hits = 9 Lines analyzed = 303 in approximately 0.02 seconds (19841 lines/second) Physical Source Lines of Code (SLOC) = 221 Hits@level = [0] 1 [1] 0 [2] 9 [3] 0 [4] 0 [5] 0 Hits@level+ = [0+] 10 [1+] 9 [2+] 9 [3+] 0 [4+] 0 [5+] 0 Hits/KSLOC@level+ = [0+] 45.2489 [1+] 40.724 [2+] 40.724 [3+] 0 [4+] 0 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
