Number of rules (primarily dangerous function names) in C/C++ ruleset: 223 Examining data/ruby-xmlhash-1.3.6/ext/xmlhash/xmlhash.c FINAL RESULTS: data/ruby-xmlhash-1.3.6/ext/xmlhash/xmlhash.c:209:3: [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(data, StringValuePtr(rb_xml), RSTRING_LEN(rb_xml)); ANALYSIS SUMMARY: Hits = 1 Lines analyzed = 248 in approximately 0.02 seconds (12326 lines/second) Physical Source Lines of Code (SLOC) = 205 Hits@level = [0] 1 [1] 0 [2] 1 [3] 0 [4] 0 [5] 0 Hits@level+ = [0+] 2 [1+] 1 [2+] 1 [3+] 0 [4+] 0 [5+] 0 Hits/KSLOC@level+ = [0+] 9.7561 [1+] 4.87805 [2+] 4.87805 [3+] 0 [4+] 0 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
