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/gkrellm-xkb-1.05/main.c FINAL RESULTS: data/gkrellm-xkb-1.05/main.c:765:5: [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(ret, ret_prop, tmp_size); data/gkrellm-xkb-1.05/main.c:68:56: [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). #define STARTS_WITH(group, flag) !strncmp(group, flag, strlen(flag)) ANALYSIS SUMMARY: Hits = 2 Lines analyzed = 775 in approximately 0.06 seconds (12240 lines/second) Physical Source Lines of Code (SLOC) = 577 Hits@level = [0] 1 [1] 1 [2] 1 [3] 0 [4] 0 [5] 0 Hits@level+ = [0+] 3 [1+] 2 [2+] 1 [3+] 0 [4+] 0 [5+] 0 Hits/KSLOC@level+ = [0+] 5.19931 [1+] 3.4662 [2+] 1.7331 [3+] 0 [4+] 0 [5+] 0 Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
