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/python-passfd-0.2/src/passfd.c FINAL RESULTS: data/python-passfd-0.2/src/passfd.c:141:5: [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 buf[CMSG_SIZE]; data/python-passfd-0.2/src/passfd.c:199:5: [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 cmsgbuf[CMSG_SIZE]; data/python-passfd-0.2/src/passfd.c:200:5: [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 extrabuf[4096]; ANALYSIS SUMMARY: Hits = 3 Lines analyzed = 241 in approximately 0.03 seconds (9034 lines/second) Physical Source Lines of Code (SLOC) = 128 Hits@level = [0] 1 [1] 0 [2] 3 [3] 0 [4] 0 [5] 0 Hits@level+ = [0+] 4 [1+] 3 [2+] 3 [3+] 0 [4+] 0 [5+] 0 Hits/KSLOC@level+ = [0+] 31.25 [1+] 23.4375 [2+] 23.4375 [3+] 0 [4+] 0 [5+] 0 Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
