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/lxhotkey-0.1.0/plugins/gtk/gtk.c Examining data/lxhotkey-0.1.0/plugins/gtk/edit.h Examining data/lxhotkey-0.1.0/plugins/gtk/edit.c Examining data/lxhotkey-0.1.0/plugins/openbox/openbox.c Examining data/lxhotkey-0.1.0/src/lxhotkey.h Examining data/lxhotkey-0.1.0/src/lxhotkey.c FINAL RESULTS: data/lxhotkey-0.1.0/src/lxhotkey.c:38:21: [4] (format) printf: If format strings can be influenced by an attacker, they can be exploited (CWE-134). Use a constant for the format specification. # define ulc_printf printf data/lxhotkey-0.1.0/src/lxhotkey.c:115:5: [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/lxhotkey-0.1.0/src/lxhotkey.c:175:5: [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 lockfile[32]; data/lxhotkey-0.1.0/src/lxhotkey.c:182:12: [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). Xnum = atoi(&display[1]); data/lxhotkey-0.1.0/plugins/gtk/edit.c:728:32: [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). if (len == strlen(opt->values->data)) ANALYSIS SUMMARY: Hits = 5 Lines analyzed = 4162 in approximately 0.12 seconds (35776 lines/second) Physical Source Lines of Code (SLOC) = 3273 Hits@level = [0] 12 [1] 1 [2] 3 [3] 0 [4] 1 [5] 0 Hits@level+ = [0+] 17 [1+] 5 [2+] 4 [3+] 1 [4+] 1 [5+] 0 Hits/KSLOC@level+ = [0+] 5.19401 [1+] 1.52765 [2+] 1.22212 [3+] 0.30553 [4+] 0.30553 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
