Consider using snprintf, strcpy_s, or strlcpy (warning: strncpy easily misused). strcpy (ns, namespace); data/lua-lgi-0.9.2/lgi/buffer.c:79:5: [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 (buffer, source, size); data/lua-lgi-0.9.2/lgi/record.c:411:6: [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 (target, record->addr, size); data/lua-lgi-0.9.2/lgi/gi.c:706:35: [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). gchar *ns = lua_newuserdata (L, strlen (namespace) + 1); data/lua-lgi-0.9.2/lgi/marshal.c:503:15: [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). len = data ? strlen(data) : 0; ANALYSIS SUMMARY: Hits = 5 Lines analyzed = 6816 in approximately 0.20 seconds (33790 lines/second) Physical Source Lines of Code (SLOC) = 5082 Hits@level = [0] 0 [1] 2 [2] 2 [3] 0 [4] 1 [5] 0 Hits@level+ = [0+] 5 [1+] 5 [2+] 3 [3+] 1 [4+] 1 [5+] 0 Hits/KSLOC@level+ = [0+] 0.983865 [1+] 0.983865 [2+] 0.590319 [3+] 0.196773 [4+] 0.196773 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
