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/jsquery-1.1.1/jsonb_gin_ops.c Examining data/jsquery-1.1.1/jsquery.h Examining data/jsquery-1.1.1/jsquery_constr.c Examining data/jsquery-1.1.1/jsquery_extract.c Examining data/jsquery-1.1.1/jsquery_io.c Examining data/jsquery-1.1.1/jsquery_op.c Examining data/jsquery-1.1.1/jsquery_support.c FINAL RESULTS: data/jsquery-1.1.1/jsonb_gin_ops.c:38:2: [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 data[1]; data/jsquery-1.1.1/jsonb_gin_ops.c:292:4: [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(GINKeyDataNumeric(key), v->val.numeric, VARSIZE_ANY(v->val.numeric)); data/jsquery-1.1.1/jsonb_gin_ops.c:357:4: [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(GINKeyDataNumeric(key), numeric, VARSIZE_ANY(numeric)); data/jsquery-1.1.1/jsquery_io.c:152:17: [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). int32 len = strlen(in); ANALYSIS SUMMARY: Hits = 4 Lines analyzed = 4833 in approximately 0.13 seconds (38292 lines/second) Physical Source Lines of Code (SLOC) = 4012 Hits@level = [0] 0 [1] 1 [2] 3 [3] 0 [4] 0 [5] 0 Hits@level+ = [0+] 4 [1+] 4 [2+] 3 [3+] 0 [4+] 0 [5+] 0 Hits/KSLOC@level+ = [0+] 0.997009 [1+] 0.997009 [2+] 0.747757 [3+] 0 [4+] 0 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
