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/xcb-util-wm-0.4.1/icccm/icccm.c Examining data/xcb-util-wm-0.4.1/icccm/xcb_icccm.h FINAL RESULTS: data/xcb-util-wm-0.4.1/icccm/icccm.c:570:3: [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(hints, (xcb_size_hints_t *) xcb_get_property_value (reply), data/xcb-util-wm-0.4.1/icccm/icccm.c:764:3: [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(hints, (xcb_size_hints_t *) xcb_get_property_value(reply), length); data/xcb-util-wm-0.4.1/icccm/icccm.c:353:18: [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). int name_len = strlen(prop->instance_name); ANALYSIS SUMMARY: Hits = 3 Lines analyzed = 1898 in approximately 0.05 seconds (39568 lines/second) Physical Source Lines of Code (SLOC) = 1001 Hits@level = [0] 0 [1] 1 [2] 2 [3] 0 [4] 0 [5] 0 Hits@level+ = [0+] 3 [1+] 3 [2+] 2 [3+] 0 [4+] 0 [5+] 0 Hits/KSLOC@level+ = [0+] 2.997 [1+] 2.997 [2+] 1.998 [3+] 0 [4+] 0 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
