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/subunit-1.4.0/c++/SubunitTestProgressListener.cpp Examining data/subunit-1.4.0/c++/SubunitTestProgressListener.h Examining data/subunit-1.4.0/c/include/subunit/child.h Examining data/subunit-1.4.0/c/lib/child.c Examining data/subunit-1.4.0/c/tests/test_child.c FINAL RESULTS: data/subunit-1.4.0/c/tests/test_child.c:40:5: [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 buffer[100]; data/subunit-1.4.0/c/lib/child.c:37:17: [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). if (details[strlen(details) - 1] != '\n') data/subunit-1.4.0/c/tests/test_child.c:76:17: [1] (buffer) read: Check buffer boundaries if used in a loop including recursive loops (CWE-120, CWE-20). bytecount = read(new_stdout[0], buffer, 100); ANALYSIS SUMMARY: Hits = 3 Lines analyzed = 553 in approximately 0.09 seconds (5906 lines/second) Physical Source Lines of Code (SLOC) = 307 Hits@level = [0] 10 [1] 2 [2] 1 [3] 0 [4] 0 [5] 0 Hits@level+ = [0+] 13 [1+] 3 [2+] 1 [3+] 0 [4+] 0 [5+] 0 Hits/KSLOC@level+ = [0+] 42.3453 [1+] 9.77199 [2+] 3.25733 [3+] 0 [4+] 0 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
