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/slcurl-0.2.1/src/curl-module.c Examining data/slcurl-0.2.1/src/version.h FINAL RESULTS: data/slcurl-0.2.1/src/curl-module.c:79:4: [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 errbuf [CURL_ERROR_SIZE+1]; data/slcurl-0.2.1/src/curl-module.c:98:4: [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 *opt_strings[NUM_OPT_STRINGS]; data/slcurl-0.2.1/src/curl-module.c:312:4: [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 ((char *) ptr, bytes, bytes_read); data/slcurl-0.2.1/src/curl-module.c:1541:12: [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 len = strlen (unescaped_string); ANALYSIS SUMMARY: Hits = 4 Lines analyzed = 1966 in approximately 0.05 seconds (40063 lines/second) Physical Source Lines of Code (SLOC) = 1582 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+] 2.52845 [1+] 2.52845 [2+] 1.89633 [3+] 0 [4+] 0 [5+] 0 Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
