Perform bounds checking, use functions that limit length, or ensure that the size is larger than the maximum possible length. char buf[50]; data/wmsystemtray-1.4+git20150508/wmsystemtray.c:256:5: [2] (buffer) char: Statically-sized arrays can be improperly restricted, leading to potential overflows or other issues (CWE-119!/CWE-120).

Use sprintf_s, snprintf, or vsnprintf. Risk is low because the source has a constant maximum length. sprintf(buf, "%d/%d", current_page+1, pages); data/wmsystemtray-1.4+git20150508/wmsystemtray.c:289:13: [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, "%d", i); data/wmsystemtray-1.4+git20150508/wmsystemtray.c:364:5: [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 hostname[256]; data/wmsystemtray-1.4+git20150508/wmsystemtray.c:373:5: [2] (buffer) char: Statically-sized arrays can be improperly restricted, leading to potential overflows or other issues (CWE-119!/CWE-120).

Risk is low because the source is a constant string. strncpy(buf, "selwindow", sizeof(buf)); ANALYSIS SUMMARY: Hits = 13 Lines analyzed = 1270 in approximately 0.05 seconds (26861 lines/second) Physical Source Lines of Code (SLOC) = 1005 Hits@level = [0] 23 [1] 3 [2] 6 [3] 0 [4] 4 [5] 0 Hits@level+ = [0+] 36 [1+] 13 [2+] 10 [3+] 4 [4+] 4 [5+] 0 Hits/KSLOC@level+ = [0+] 35.8209 [1+] 12.9353 [2+] 9.95025 [3+] 3.9801 [4+] 3.9801 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
